Juventus defender Andrea Barzagli believes Champions League opponents Chelsea are even stronger this season.

Barzagli feels they have more than covered the departure of Didier Drogba with the likes of Eden Hazard and Oscar.

"Yeah, they were strong, but they are even more so now, they're unbeaten in the league. And then they also have great experience playing in the Champions League," said Barzagli.

"It will be my first trip to Stamford Bridge and my first game against Chelsea. At my age I keep my emotions in check, but also I know the importance of this occasion."
