Tottenham were not at their Real Madrid-beating best, but Son Heung-min's strike was enough to see off Crystal Palace.
Paulo Gazzaniga played an unlikely hero act for Tottenham, repelling a dogged Crystal Palace before Son Heung-min struck to secure a 1-0 win at Wembley.
Dele Alli's absence from the teamsheet will have perturbed Spurs fans, but Gazzaniga's presence was most eye-catching, the former Southampton goalkeeper making his Spurs debut in place of the injured Hugo Lloris and Michel Vorm.
Gazzaniga had not played in the Premier League since December 2015 and overcame a rocky start to deliver a fine performance, making three excellent saves to stop Palace opening the scoring.
