Tottenham's league form was average at best: having stood in third place after 17 games, the club won only three of their next 21 league matches, slumping to tenth place in the final table. The club had better luck in the FA Cup: after defeating London arch-rivals (and that season's eventual champions) Arsenal in the semi-final, they defeated Nottingham Forest 2-1 in the final. As well as giving Tottenham their first post-Heysel European campaign (in the Cup Winners' Cup) and ending the club's seven-year trophy drought, the FA Cup win made Tottenham the first club to win the trophy eight times, although this record has since been surpassed by Arsenal and Manchester United.
The only downside of the FA Cup triumph was an injury to star midfielder Paul Gascoigne, who ruptured his cruciate ligaments in a tackle on Forest fullback Gary Charles early in the first half. The injury would put his transfer to Italian side Lazio on hold until the 1992–93 season. Gascoigne had earlier scored a tremendous free-kick in the 3–1 win against Arsenal in the semi-final (Gary Lineker scored Tottenham's other goals, with Arsenal's Alan Smith scoring Arsenal's goal).
The FA Cup final saw Tottenham debut a longer style of shorts as part of their kit. Although the long shorts were ridiculed at first, within the decade all clubs in English football would have adopted the style.
