Claudio Ranieri admits his European preparations have been dealt a blow by the goings-on at Chelsea.
The Juventus boss is set to go head-to-head with the Blues in the last 16 of the UEFA Champions League.
While the turmoil at Stamford Bridge, which resulted in Luiz Felipe Scolari's sacking on Monday, would suggest the Premier League outfit are there for the taking, Ranieri does not believe that is the case.
The experienced Italian, himself dismissed by Chelsea in 2004, believes the uncertainty surrounding who will be in charge of the Blues by the time Juve head to London on 25th February makes it difficult for him to prepare properly for the tie.
"We could have done without this change," said Ranieri.
"Now the players will have an excuse and I, who had studied Scolari's team by memory, will have to start from the beginning.
"It will be another Chelsea and I will only have two weeks to get to know it."
Juve keeper Gianluigi Buffon is also expecting a tough test against the Blues and believes the Chelsea players will be keen to make amends for their recent failings.
"It would have been better if he [Scolari] had been sacked after they hadn't got through to the next round," said the Italy international.
"However, in my opinion a change of manager means the team aren't doing well, that's what normally happens.
"Usually when a team changes manager they're weakened but their desire isn't, so we'll have to see.
"I don't know if it will favour Juve. You will only be able to tell that after the game unfortunately.
"But a change in manager normally provokes a reaction and in this case, looking at the players Chelsea have, I think it will have a positive effect."
