Chelsea manager Rafael Benitez believes that Swansea City will be tough to beat in the semi-finals of the League Cup.

The Blues will take on their Premier League rivals for a place in the final of the competition in January.

"When you go to a semi-final, any team will be difficult," he told Chelsea's official website. "Swansea is a good team who try to play football, and because we are so close to the final their motivation will be there.

"The first thing I have to do is beat Swansea, but to win trophies is important for any manager. First we must concentrate on the semi-final and after that we can talk about the final."

Chelsea beat Leeds United 5-1 at Elland Road in the quarter-finals on Wednesday.
