On 17 September 2006, a 17-year-old Witsel made his debut with Standard Liège during a competitive game against FC Brussels when he replaced Steven Defour in the 89th minute. Eleven days later, he made his European debut as a substitute.[citation needed]
During the 2007–08 season, at 18 years of age, he was a key member in the squad of Standard Liège, winners of the Belgian League title that year. During this year, he formed a very young midfield together with other Belgian talents Defour and Marouane Fellaini. In the following season, he scored the winning goal from the penalty spot in a two-legged playoff to decide the championship.[citation needed]
On 30 August 2009, Witsel sparked controversy when he broke Marcin Wasilewski's leg by stamping on his ankle during the match between Anderlecht and Standard.[5][6] Following the tackle, Witsel protested the red card, claiming that it was an accident without intent, before being sent off the pitch. He soon apologised, but was the subject of criticism from several media outlets and numerous death threats from angry Anderlecht and Poland fans.[7] The initial ban until 23 November by the Belgian Football Association,[8] was later reduced on appeal to eight matches.[9]
Benfica
Witsel signed for Portuguese club Benfica on a five-year deal on 13 July 2011, including a €40 million buyout clause.[10] Witsel scored twice in the 3–1 win against FC Twente, in the Champions League play-off second leg, on 24 August 2011, sending Benfica to the group stages with a 5–3 aggregate victory.[11]
He scored the opening goal in a 4–1 thrashing of Vitória de Guimarães in the Taça da Liga on 9 January 2012.[12] He then assisted Nolito in a 4–1 league defeat of Vitória de Setúbal. Witsel scored his fourth goal against Santa Clara on 18 January in a Taça da Liga match.[13] Benfica reached the final on 14 April against Gil Vicente and Witsel was awarded the Man of the Match award as Benfica claimed their fourth Taça da Liga title with a 2–1 victory.[14]
Zenit Saint Petersburg
On 3 September 2012, Witsel signed for Zenit Saint Petersburg for €40 million, after signing a five-year contract.[15][16] Witsel made his debut in the Russian Premier League on 14 September, replacing Konstantin Zyryanov in the 70th minute as Zenit fell 2–0 to Terek Grozny.[17] He scored his first two goals for the club on 30 November when Zenit brushed aside Spartak Moscow 4–2 at the Luzhniki Stadium.[18] Witsel scored Zenit's winner against Terek Grozny on 30 March 2013, an eighth-minute strike, as his side cruised to a 3–0 league victory.[19]
In Zenit's first match of the 2014–15 UEFA Champions League group stage on 16 September 2014, Witsel scored Zenit's second goal in a 2–0 away victory over former club Benfica.[20] After finishing third in their Champions League group, Zenit were parachuted into the Europa League knockout phase; in the first leg of their Round of 16 clash against Torino on 12 March 2015, Witsel scored on a rebound as Zenit defeated the Italian club 2–0.[21] On 26 April, Witsel scored the game's only goal in the seventeenth minute as Zenit defeated Arsenal Tula in a league match at the Petrovsky Stadium.[22] On Sunday 17 May, Witsel played the full 90 minutes as Zenit drew 1–1 with FC Ufa, earning the point they needed to secure the Premier League crown, the club's fourth overall and Witsel's first with Zenit.[23]
On 6 August 2018, Witsel signed for Bundesliga club Borussia Dortmund and agreed a four-year contract which would last until 30 June 2022.[28][29] On 21 August, he scored an equalizing goal in the stoppage time to make it 1–1 after coming on as a substitute on his debut for the club against SpVgg Greuther Fürth in the DFB-Pokal first round match and later his side went on to win the match in the extra time with a 2-1 victory.[30] Witsel scored his first Bundesliga goal on his league debut for the club with an overhead kick in a 4–1 victory over RB Leipzig on 26 August.[31]
Atletico Madrid
On 7 July 2022, Atlético Madrid officially announced that Witsel had signed for the club on a one-year contract via a free transfer after his contract with Borussia Dortmund expired.[32] Under manager Diego Simeone, Witsel began to play as a defender in the middle of a back three in the 5–3–2 formation.[33][34] On 13 June 2024, he extended his contract until 2025.[35]
International career
Prior to making his international debut for the senior side, Witsel played for the under-21 side in 2007, earning nine caps as well as helping his side reach the semi-finals of the 2007 UEFA European Under-21 Championship.
On 26 March 2008, Witsel made his senior international debut for Belgium during a friendly game against Morocco. The match resulted in a 1–4 loss, but Witsel scored his first goal.[36]
Witsel's first goal in a competitive international match came a day short of three years after the Morocco goal, in the sixth minute against Austria in Group A of the UEFA Euro 2012 qualifying process, and his second would come in the second half.[37] However, Belgian hopes of qualifying for UEFA Euro 2012 were dashed on 11 October 2011, by defeat to Germany coupled with Turkey's victory over Azerbaijan.[38]
On 12 May 2023, Witsel announced his retirement from the national team on Instagram, having made 130 appearances for Belgium.[46] However, Witsel would later reverse his decision and on 28 May 2024, he was included in Belgium's squad for UEFA Euro 2024.[47]
