Crystal Palace ended Tottenham’s hopes of a treble as Martin Kelly’s first-half strike sent the Eagles into the last eight of the FA Cup.
The defender scored his first goal since November 2011 when he thrashed in from six yards just before half-time after Wilfried Zaha had played him in.
Spurs went close on several occasions, with Dele Alli’s first-half shot striking both posts.
Harry Kane had two strikes brilliantly pushed away by keeper Wayne Hennessey.
Palace are in the FA Cup last eight for the first time since 1995, and this was their first win at White Hart Lane since 1997.
Mauricio Pochettino’s side are the stingiest in the Premier League – having only conceded 20 times – but the defending was shambolic at times today.
