The campaign featured Tottenham's first ever involvement in the UEFA Champions League, with the club entering via the play-off round after finishing fourth in the 2009–10 season. The club reached the quarter finals of the competition where they were defeated by Real Madrid.

Tottenham began their transfer movement for the 2010–11 season in mid-March, when Spurs completed the deal for young Brazilian midfielder Sandro, joining the club from Internacional, a club whom Tottenham have a key affiliation, with Sandro linking up with squad following the 2010 Copa Libertadores. Early in the transfer window, Tottenham retained the services of a number of key players, with club captain Ledley King signing a new two-year contract extension with the club, closely followed by former Chelsea goalkeeper Carlo Cudicini, who signed a new one-year contract following his recovery from a serious road accident sustained in November 2009.

Luka Modrić was the next player to commit his future with the club, signing an extended six-year deal to ensure his services until 2016. After two months of little transfer activity, Tottenham secured the controversial signing of William Gallas on a free transfer following his release from rivals Arsenal. As a result of the move, Gallas became the first Premier League player to play for Chelsea, Arsenal and Tottenham Hotspur, all London clubs and fierce rivals. On transfer deadline day, early in the day, Spurs confirmed the loan signing of Croatian international goalkeeper Stipe Pletikosa from Spartak Moscow. This looked to be Spurs' only move of the day, but in the final few moments before the deadline, news broke that Tottenham were in negotiations with Real Madrid midfielder Rafael van der Vaart. Following the closure of the transfer window, the club had to wait for the deal to be ratified by the Premier League, due to complications on Spurs' computer. The transfer was completed the next day, with fee believed to be around £8 million.
