Chelsea manager Jose Mourinho has praised his side's League Cup semi-final victory over a "very difficult" Liverpool side, despite claiming that it should not have gone to extra time.

The two Premier League giants could not be separated by 180 minutes of football, but Branislav Ivanovic's goal in the 94th minute of the second leg ultimately saw the Blues win 2-1 on aggregate and reach the final.

Mourinho told Sky Sports News after the game: "This is a new Liverpool team and a very difficult opponent. So I'm even happier because we beat a very good team over two legs.

"The difference was the goal that should have happened before in the 90 minutes. In the second half we had a lot of football."

Chelsea will face either Tottenham Hotspur or Sheffield United in the final at Wembley in March.
