Sir Alex Ferguson: Extra time too much for Man Utd's young side

Manchester United manager Sir Alex Ferguson says being knocked out of the League Cup by Chelsea was a "sore lesson" for his "young" side.

Chelsea made two defensive errors as Ryan Giggs and Javier Hernandez scored either side of David Luiz's penalty. Gary Cahill made it 2-2 but it appeared Nani's chipped finish would win it, before Eden Hazard's spot-kick.

Daniel Sturridge and Ramires both registered in extra time before Giggs added a late consolation penalty, with the match finishing 5-4 to the Blues.
