Chelsea boss Roberto di Matteo admits they risk humiliation against Champions League opponents Juventus.

Chelsea must rely on the constitution of a team that won the European Cup, turning to Cech, Cahill, Luiz, Ashley Cole and John Mikel Obi to get them out of a spot of bother.

Di Matteo said: "We have plenty of players who can be leaders on the pitch and everyone will have to show that in a game like this. Cech is there, but we have Ivanovic and Mikel, who have been playing for many years now - and Mata as well.

"Nobody wants to be the first holders to be knocked out of the group stage."
