Marcus Åke Jens-Erik Nilsson (born 26 February 1988) is a Swedish football manager and former player who played as a centre-back and since 2018, he has joined Eskilsminne IF .

[2] Nilson appeared as an unused substitute in the Svenska Supercupen, as the club lost 1–0 against Elfsborg on 31 March 2007.

[5] The 2008 season saw Nilsson struggling to make a breakthrough in the first team, with the likes of Joel Ekstrand, Andreas Granqvist and Samir Beloufa established himself in the central defence position.

[6] Following the departure of Granqvist and the arrival of Hannu Patronen, he made his first appearance of the season, starting the whole game, in a 1–1 draw against Göteborg on 8 July 2008.

[7] From July to October, Nilsson had a handful of first team appearances and formed a central defence partnership with youngsters, Ekstrand.

[10] He then helped the club keep three clean sheets in the three matches between 29 April 2009 and 11 May 2009 against AIK, Malmö and IF Brommapojkarna.

At the start of the 2010 season, Nilsson was in defensive first team position when he helped Helsingborgs IF keep four clean sheets in the first four league matches.

[23] However, his return was short–lived when he was suspended for a match against BK Häcken on 26 July 2010 for picking up five yellow cards this season.

[24] Despite being suspended twice during the 2010 season, Nilsson continued to regain his first team place for Helsingborgs IF, forming a centre–back partnership with Ekstrand and helping the club to keep their league title chance alive.

[25] However, in the last game of the season against Kalmar, he started the whole game and helped Helsingborgs IF keep a clean sheet, in a 0–0 draw but cost the club to win the league title, as title contender rival, Malmö FF, won the league following their win.

[26] In a follow–up match, Nilsson started in the Svenska Cupen Final against Hammarby and helped Helsingborgs win the tournament by beating the opposition team 1–0 on 13 November 2010.

[35] His last appearance for the club in a wake of his transfer move came on 18 July 2011 against Kalmar, in a 2–1 win, which Nilsson was in tears as a result.

[44] Despite making sixteen appearances in all competitions, Nilsson, however, was named as the league's worst signing of the season by Voetbal International.

[57] His performance led Kalmar signing the player on a permanent basis, keeping him until the end of the season.

[59] Despite being sidelined with suspensions and injuries, Nilsson finished his first season at the club, making twenty-six appearances and scoring once in all competitions.

[60] Ahead of the 2015 season, Nilsson signed a contract extension with Kalmar FF, ending the transfer rumours that he could leave the club.

[62] In a match against his former club Helsingborgs IF on 31 July 2015, Nilsson was involved in an incident with the opposition's supporters, resulting an apology from the player.

[80] Only weeks after leaving Stabæk, Nilsson joined K League Classic side Pohang Steelers on 25 January 2017, with the contract length were not disclosed.

[81] However, he made no appearances for the club, due to injuries and on 2 June 2017, Nilsson's contract was officially terminated by mutual consent.

[82] Following his release from the club, he returned to Sweden and said in an interview with Expressen on whether to continue his football career or not, saying: "I expect to rehabilitate in January, then I will be able to be healthy.

When sports director Kalle Olsson came up with the proposal that we would make a solution where, in addition to being a potential player, I would also take the assistant job, I decided to say yes.

[88] Nilsson made his first appearance of the 2020 season, starting a match and played 76 minutes before being substituted, in a 4–1 loss against GAIS in the Svenska Cupen on 8 March 2020.

[89] The 2020 season was pushed back, due to the pandemic, allowing the player to heal from his injury that he sustained prior to this.

[107] The following month, on 22 January 2011, he made his (and only appearance) debut for the national side, coming in a 1–1 draw with South Africa.
