Tottenham are celebrating reaching Wembley.
Tottenham Hotspur are heading to Wembley after a 3-2 aggregate win at Bramall Lane.
Spurs had been leading 1-0 at half-time and 2-0 overall before the Blades threatened to take it to extra time with a quick fire brace in the second half.
It set up for a nervous finish with Sheffield United on the ascendancy before a superb Harry Kane pass set up Christian Eriksen for a crucial late goal.
Tottenham face Chelsea in the final, who beat Liverpool a day earlier 2-1 on aggregate after extra-time.
Roberto Soldado, who did not start the game but did win the decisive penalty in the first leg, was the first player of many to send out a photo of the celebrations inside the dressing room after the final whistle, with goalkeeper Michel Vorm in the foreground.
Spurs beat Chelsea 5-3 on New Year’s Day, but lost to them 3-0 at Stamford Bridge, with the game set up as a repeat of the 2008 League Cup final, in which Tottenham emerged victorious.
