Former Chelsea boss Gianluca Vialli is looking forward to the big Champions League clash with Juventus.

Vialli is a legend with both clubs.

"It will be a match between two teams who have to face a challenge. Juventus are back in the Champions League after a few years. While Chelsea starts without its leader, Didier Drogba.

"The Blues have changed a lot, buying players that can liven up their play: Hazard, Marin, Oscar. All fast players called to trigger Torres.

"This is also a gamble: they bet everything on the Spaniard."
