Nacer Chadli (Arabic: ناصر الشاذلي; born 2 August 1989) is a Belgian professional footballer who plays as a winger for Standard de Liège 16 FC.

Chadli began his career in the Eerste Divisie with AGOVV Apeldoorn, and in 2010, was transferred to top-flight FC Twente, where he won the KNVB Cup in his first season.

While Chadli was being tested by AGOVV, he went under the alias "Kaliffe", because technical manager Ted van Leeuwen was afraid other clubs would show their interest.

[12] The club confirmed that subject to agreement of personal terms and a medical, Chadli would join the Spurs squad for pre-season training in Hong Kong.

[14] Chadli finally agreed terms on 26 July and became an official Tottenham player, later making his Spurs debut in a 5–2 friendly defeat to AS Monaco on 3 August.

[18] This was the start of a run of good form for Chadli, who went on to score several goals, including one against Tottenham's North London rivals Arsenal.

[19] Chadli slowly returned to form, scoring two goals in two matches against Newcastle United and Southampton, respectively, in late April to take his season total to 12, ten in the Premier League.

On 29 August 2016, West Bromwich Albion agreed a deal with Tottenham Hotspur to sign Chadli for a club-record transfer fee of £13 million.

[21] Chadli scored twice and got two assists on his home debut, only his second league appearance for the club which ended as a 4–2 win over West Ham United.

[22] In 2017–18, Chadli was troubled by recurring thigh injuries and made only three appearances by the end of April in a West Bromwich Albion side that was eventually relegated.

He made his debut for Morocco on 17 November 2010, in a 1–1 friendly draw against Northern Ireland at Windsor Park,[38] and was named man of the match.

[40] Chadli has played as a striker for the Belgium national team,[41] scoring his first international goal in a UEFA Euro 2012 qualifier against Azerbaijan in the King Baudouin Stadium in Brussels on 29 March 2011.

[43] He started in midfield but was substituted at half time for Dries Mertens in the team's first game of the tournament, a 2–1 win over Algeria in Belo Horizonte.

[45] On 2 July 2018, Chadli came off the bench to score the winning goal in injury time to lift Belgium to a 3–2 victory over Japan in the round of 16 of the 2018 FIFA World Cup.
