The Italian believes that the Blues' status as the reigning European champions will motivate the opponents to raise their game against them.
"We will be a scalp for the teams now," he is quoted as saying in The Mirror. "The motivation of the other teams will be stronger because we are the holders.
"I am sure a lot of managers will use that to motivate their players."
Chelsea were held to a 2-2 draw by Juventus at Stamford Bridge in their opening Group E game earlier this month.
