New Chelsea signing Gary Cahill admits he's excited to be playing in the Champions League.

The former Bolton Wanderers defender has immediately set his sights on testing himself against Europe's best.

"That's the whole reason you want to move," he told Chelsea TV. "You want to play at the top level and the Champions League is the top level.

"I've only played in Europe when I first moved to Bolton; (Atletico) Madrid away, Sporting Lisbon, teams like that.

"It'll be a new experience for myself, and I'm looking forward to pitting my wits against the top players in the world."
