Bamidele Jermaine Alli (born 11 April 1996) is an English professional footballer who plays as a midfielder.
On 2 February 2015, Alli signed for Premier League club Tottenham Hotspur in the last hours of the mid-season transfer window on a five-and-a-half-year deal for an initial fee of £5 million.
Following his transfer to Tottenham Hotspur, Alli was immediately loaned back to MK Dons for the remainder of the 2014–15 season. On 19 April, he was chosen as the Young Player of the Year at the Football League Awards.
On 8 August 2015, Alli made his Tottenham debut against Manchester United in the Premier League as a substitute in a 1–0 defeat away at Old Trafford, playing the last 13 minutes in place of Eric Dier. Two weeks later, he scored his first goal for the club after coming on for Christian Eriksen in the 1–1 draw against Leicester City.
On 13 September, Alli made his first start for Tottenham in a 1–0 win against Sunderland at the Stadium of Light. On 2 November, he started and scored the second goal in an eventual 3–1 win over Aston Villa. Six days later he started his first North London Derby alongside fellow England youngster Dier in central midfield, and was awarded Man of the Match in the 1–1 draw between rivals Arsenal and Tottenham. On 5 December 2015, he scored his third goal for Tottenham in the 2015–16 campaign in a 1–1 draw against West Bromwich Albion at The Hawthorns.
Following an impressive start to his Premier League career scoring five goals and making three assists in his first 18 league matches, he was rewarded with a new long-term contract until 2021 on 12 January. Eleven days later he scored a 25-yard volley in a 3–1 win at Crystal Palace; BBC Sport pundit and former Spurs player Garth Crooks wrote "Well, I've seen some glorious goals scored in my time watching football matches but I doubt whether I will see a goal scored with such individual flair, and by a 19-year-old, as Dele Alli's goal at Selhurst Park – it was sheer class". On 13 April, he was named on the six-man shortlist for 2015–16's PFA Young Player of the Year.
On 18 April 2016, he scored his first brace for Tottenham in a 0–4 away win at Stoke City, reaching ten goals in his debut Premier League season. He was voted the season's PFA Young Player of the Year. On 28 April, Alli was banned by the Football Association for three matches, effectively ending his Premier League season, for an off-the-ball incident against West Bromwich Albion in which he punched midfielder Claudio Yacob in the stomach. He later apologised for the incident on Twitter, stating, "Gutted that my season is over. Shouldn't have reacted like I did. Will learn from this and come back stronger."
Ahead of the season, Alli changed his kit name to Dele, saying that he had "no connection" to his legal surname due to his separation from his mother. His first goal of the season came in a 4–0 win against Stoke City on 10 September 2016. Four days later, he made his UEFA Champions League debut in a 1–2 loss to AS Monaco at Wembley Stadium. His first Champions League goal came against CSKA Moscow at the same stadium on 7 December 2016. Between 18 December 2016 and 21 January 2017, Alli scored eight goals in six league matches, earning the Premier League Player of the Month award for January 2017. This included three consecutive braces against Southampton, Watford and Chelsea.
On 23 February, Alli received his first red card for a dangerous tackle on Brecht Dejaegere in Tottenham's UEFA Europa League draw with K.A.A. Gent which saw Spurs eliminated at the Round of 32 stage of the competition. On 20 April 2017, Alli was again named in the PFA Team of the Year, having been included in the League One selection for 2015 and the Premier League selection in 2016. On 23 April, he was named the PFA Young Player of the Year, the day after scoring in Tottenham's 4–2 FA Cup semi-final loss to rivals Chelsea at Wembley Stadium.
Alli scored his first goal of the season in the opening game of the 2017–18 season away at Newcastle that finished in a 2–0 win. However, he was criticised for his inconsistency this season, failing to perform as well as the previous season. On 1 April 2018, Alli scored twice in the away fixture against Chelsea, helping Tottenham win 3–1, which was their first win in 28 years at Stamford Bridge.
On 11 August 2018, Alli scored his first goal of the season, scoring the winning goal in the opening league match against Newcastle United.
On 26 September, Alli was named as captain for Tottenham's EFL Cup third round tie with Watford. The tie, played at Stadium MK due to delays in the completion of Tottenham's new stadium, marked Alli's return to the home ground of his boyhood club MK Dons, and the return to his home town of Milton Keynes for the first time as a Tottenham player. The tie finished 2–2, with Alli scoring both a penalty in normal time and the winning penalty in a deciding penalty shoot-out.
In October 2018, Alli signed a new six-year deal at Tottenham, which would keep him at the club until 2024. He also scored in the 3–1 home win against Chelsea, which was his sixth goal in five games against Chelsea, and the first defeat for Chelsea in the Premier League that season. In January 2019 he was ruled out until March with a hamstring injury.
Alli missed the start of the season due to a hamstring injury. He returned to the team in the North London Derby on 1 September 2019, coming on as a substitute. He scored his first goal of the season in the match against Watford, drawing 1–1. In November 2019, manager Mauricio Pochettino was dismissed by the club to be replaced by José Mourinho. Mourinho played Alli as an attacking player just behind Harry Kane, reverting to his earlier position after playing in a deeper midfield role the previous two years. According to Mourinho, "Dele is not a midfield player". The attacking role gave Alli greater freedom to score, and he scored three goals in his first three games under Mourinho, two of which came in a 3-2 win against Bournemouth.
In February 2020, shortly after the COVID-19 pandemic began, Alli posted a video on Snapchat in which he joked about the outbreak and appeared to mock an Asian man. Alli later deleted the post and released a video apology on Weibo. He was charged with misconduct by the Football Association over the incidence.
