Luc Castaignos (born 27 September 1992) is a Dutch professional footballer who plays as a forward for 2. Bundesliga club 1. FC Magdeburg.

Club career

Early career

The roots of Castaignos' family are located in the département of Landes, one hundred kilometers south of Bordeaux in the south-west of France. There, Castaignos' father, the French-born Jean-Luc Castaignos, met Castaignos' mother who is of Cape Verdean descent and holder of an Italian passport. In October 1990, two years before Luc's birth, the family moved to the Netherlands.

Castaignos started his youth career at the local Schiedam club Excelsior '20. The youngster lived close to Sportpark Thurlede, the home ground of the Catholic club. His former Excelsior '20 coach, Paul Benschop, was soon convinced by Castaignos' quality: "Everyone could see how much potential he had. Whenever we conceded a goal, Luc would take care of business." At the age of 13, he participated on regional club Spartaan '20's opening day. The club from Rotterdam, youth partner of Feyenoord, saw plenty of potential in the youngster and invited him to join. Castaignos only played one season for Spartaan '20. When various professional clubs showed their interest, Spartaan '20 warned Feyenoord. At the age of 14, he joined the Feyenoord Academy in the summer of 2007. On 30 October 2008, Castaignos signed his first professional contract with Feyenoord, keeping him at De Kuip until summer 2011 with an option for another two seasons. He then progressed through the academy.

Feyenoord

After a successful performance with the Netherlands U17 at the 2009 UEFA European Under-17 Football Championship, a clutch of sides were linked to the Dutch youngster. Besides Arsenal, also Liverpool, Manchester United, Real Madrid, Inter Milan, Bayern Munich and TSG 1899 Hoffenheim showed their interest in the Feyenoord's top scorer. However, on 22 July 2009, Castaignos crushed all rumours and told Feyenoord manager Mario Been and technical advisor Leo Beenhakker that he wanted to stay in Rotterdam. On 21 June 2009, Been announced he invited Castaignos to train with the first team squad a few times a week. On 13 August 2009, he trained with the first team squad for the first time. Castaignos made his official debut in Feyenoord's first team on 24 September 2009 replacing Leroy Fer in the 72nd minute in the KNVB Cup away match against Harkemase Boys and helped the club win 5–0. After making his first team debut for Feyenoord, he said: "It's strange, because I haven't really proven anything yet. My strengths are my speed and scoring ability, the heading and my left leg could be even better. I can learn a lot from a player like Roy Makaay. Now and then I ask for advice, but I mainly look at the training at which moments he walks away and so on. My debut is a first step, but there are still many steps to follow." At one point, due to his lack of first team opportunities, Castaignos was expected to be loaned out to SBV Excelsior but he ended up staying at the club due to his latter injury. Five months later after making his first team debut and being on the unused bench, Castaignos made his debut, coming on for Jon Dahl Tomasson in a 3–2 loss against Groningen on 28 February 2010. A month later on 24 March 2010, he made his first start of the season against FC Twente in the second leg of the KNVB Cup semi–finals and helped the club win 2–1 to reach the final. Later in the 2009–10 season, Castaignos would make two more appearances and the club would finish in fourth place.

The 2010–11 season campaign proved to be Castaignos' breakout season, stemming from squad rotation and losses in the transfer market. He made his UEFA Europa League debut, coming on as a 77th-minute substitute, in a 1–0 win against Gent in the first leg of the play-off rounds (as Feyenoord went on to lose 2–0 in the return leg and was eliminated from the tournament). Following the club's elimination in the UEFA Europa League, Castaignos scored his first career goal for Feyenoord, in a 4–0 win against Vitesse on 28 August 2010. As a result, the club began talks with the player over a new contract. However, he rejected a contract extension, leaving his future at Feyenoord uncertain. Amid to the contract rejection, he scored three goals in three matches between 31 October 2010 and 14 November 2010 against AZ Alkmaar, Roda JC and SC Heerenveen. Castaignos changed his mind when he signed a contract extension with the club, keeping him until 2013, but his agent disputed the claims that the deal was done. Castaignos later scored two more goals by the end of the year, coming against ADO Den Haag on 28 November 2010 and SBV Excelsior on 11 December 2010. In a friendly match against Sparta Rotterdam on 5 January 2011, he received a straight red card in the 57th minute for kicking an opponent, in a 4–2 win. After the match, Castaignos was investigated for his actions by the KNVB, but no action was taken against him. During the same month, he suffered ankle injury while training but quickly recovered from the injury. A month later against Vitesse on 6 February 2011, Castaignos scored his seventh goal of the season, in a 1–1 draw. Two weeks later on 20 February 2011, he scored his first brace of his career, in a 2–2 draw against ADO Den Haag. Two weeks later on 6 March 2011, Castaignos scored his tenth goal of the season, in a 1–0 win against SC Heerenveen. This was followed up by scoring his eleventh goal of the season, in a 2–1 win against NAC Breda. He went on to score four goals in the last four matches of the season that saw Feyenoord finish 10th place in the league, missing out on the Europa League in the process. At the end of the 2010–11 season, Castaignos went on to make 37 appearances and scoring fifteen times in all competitions. He later said in an interview about his desire on returning to Feyenoord one day.

Inter Milan

As a result of rejecting a new contract with Feyenoord, Castaignos was on the rampant speculation during the January transfer window, with Italian giants Inter Milan, PSV Eindhoven, Tottenham Hotspur and Valencia were interested in signing the player. In the January transfer window, Inter Milan had their €3 million bid rejected by Feyenoord for Castaignos. After months of agreement, it was finally announced on 4 March 2011 by Feyenoord that the club had agreed to terms with Inter Milan, selling the player for a fee believed to be around €3 million upon the completions of the 2010–2011 season. Upon joining the club, he said: "As a striker you always want to score, but I had hoped to say goodbye with European football. The choice for Inter was a choice based on feeling. I hope that I can become a better football player there. Of course I am really looking forward to going in that direction and developing myself as footballer. I want to become a top player."

Castaignos was featured throughout preseason, most notably scoring the opening goal in a friendly against Celtic on 30 July 2011. He made his competitive debut for Inter Milan in a Supercoppa Italiana, coming on for Joel Obi in a 2–1 loss against Milan, and played in front of 70,000 people at Beijing National Stadium, Beijing China PR. However, Castaignos was controversially dropped from the UEFA Champions League squad. This led the club's chairman Massimo Moratti commenting on the situation on the player, saying: "I was very sorry for Castaignos because he is a great guy, if this story came up he would play him. It's pretty bad, but it's not like you hit someone. We just have to avoid these things." Despite hops of his inclusion in the squad for the tournament, Castaignos remained out of the squad. He made his full league debut, starting a match before being substituted at half time, in a 3–1 loss against Novara on 20 September 2011. Castaignos then scored his first goal in Serie A in an away match to Siena on 27 November 2011, latching on to Thiago Motta's through ball before firing low past Brkić, which proved to be the game winner. However, Castaignos found his first team opportunities limited, due to competitions in the striker positions.

As a result of his lack of first team opportunities, Castaignos was linked a move away from the club, as European clubs from Italy and his homeland country, including PSV Eindhoven were interested in signing him. Ultimately, he stayed at Inter Milan after his agent ruled out of suggestions about the player being loaned out. During a 3–0 loss against Bologna on 17 February 2012, Castaignos was involved in altercation with Andrea Raggi after he spat on Raggi in the 85th minute. After the match, Serie A officials reviewed footage of the incident and he was subsequently banned for three matches. Even after serving a three match suspension, his actions caused Inter to immediately move him into a reserve role, scoring twice in three appearances for the reserve squad and only playing once in the league. However, Castaignos then suffered a hamstring injury, missing out for the rest of the season during a match against Padova Primavera on 4 April 2012 and was sidelined for the rest of the 2011–12 season. At the end of the 2011–12 season, he went on to make eight appearances and scoring once in all competitions.

Following this, his future at Inter Milan was uncertain when Castaignos was linked with a move away from the club. It came after when he was linked with a move to clubs around Premier League clubs, such as, Liverpool, West Ham United, Everton and even his former club, Feyenoord.

Playing style

Castaignos' playing style led the media to compare him to Thierry Henry. However, he received criticism from the Netherlands media failing to live up to his potential, as well as, his performance.

Former Feyenoord striker Roy Makaay said about the player, saying: "He has an awful lot of qualities, but also shortcomings. The great thing is that he sees that himself. A good quality. Initially, Luc could only stand on his left leg, but recently he has already developed in that area. More is expected of him than is realistic with his age. That applies to more guys at Feyenoord and that creates enormous pressure. Then things are not going well, the results are not really good and that pressure will only increase. He has a lot of qualities, but also shortcomings. The good thing is that he sees it himself. A good feature. Initially Luc could only stand on his left leg, but lately he has already developed in that area." Then Feyenoord manager Mario Been said about Castaignos, saying: "He is getting better and better, I am actually only waiting for a goal. I will just let Luc be in the front line for the coming period. If he makes a few, he can do so enormously help out. Luc fends off in the duels with big defenders, uses his body better and better. He clearly has the qualities for it."

Castaignos spoke about his physical appearance in his early Feyenoord's career, saying: "You demand a lot from your body in such a football year. I notice at the top how important it is to have strength.Especially since I am not yet fully grown due to my age and still have to gain a few kilos of muscle strength. That is where my gains are in the coming seasons. I already notice that I have become stronger. At the beginning of the competition I was pushed away more easily then now." Manager Been said: "We only had Luc as a deep striker. Now he can handle it physically well. He's getting stronger and holding his own." Manager Steve McClaren said about the Castaignos, saying: "Luc Castaignos is also doing well. We like what we see of him in training, he is a real striker who wants to score continuously. He is working on his fitness and needs some time."

Regarding his failed spell at Inter Milan, former Feyenoord striker Pierre van Hooijdonk said: "The problem with Luc Castaignos is that people see him as a player who comes from Inter. And that is not right, because that is not his shoe size. You have to judge him as a Feyenoord player and not with an Inter shirt on, because that has never been his level. The problem with Castaignos is that he doesn't score enough at the moment. If that is the case, other things are looked at and a striker is criticized for his playing football. You never hear that about a striker who has twenty in it." Makkay also said about the striker's time in Italy: "I cannot judge what he did in Italy that year. But he has hardly played. And for a young player it is of course important to play many matches. On the other hand, he was able to train at a high level at Internazionale."

Then Eintracht Frankfurt Manager Armin Veh said: "He can combine, play as a second tip or come over the left wing. We are very variable there", while manager Gertjan Verbeek called him "a second striker".

Personal life

In March 2011, Castaignos and his then teammate Ron Vlaar took part in a spinning marathon for the charity, Stichting Luna Sluiter Foundation.

Upon joining Inter Milan, he began learning Italian. Growing up, Castaignos said he idolised Samuel Eto'o. In January 2014, Castaignos got his wisdom tooth removed and missed FC Twente's pre–season winter for three days.
