Leicester came from two goals behind to beat Tottenham 3-2 in the FA Cup third round match at the Walkers Stadium.
Spurs had taken the lead through Jermaine Jenas in the 20th minute before Paul Stalteri added a spectacular second with a 20-metre screamer five minutes from the break.
But Elvis Hammond pulled a goal back for the Coca-Cola Championship strugglers moments before half-time and Stephen Hughes hauled the Foxes' level with an assured second-half strike
Spurs, knocked out of the League Cup by Grimsby earlier in the season, completed a miserable double when Mark de Vries broke clear to tuck in the winner in injury time.
