Chelsea goalkeeper Petr Cech has warned teammates not to be distracted by Juventus coach Claudio Ranieri's emotional return to Stamford Bridge.
He said: "I arrived after he left, but a few of the lads played under Ranieri and I think it will be a special night for him and the supporters because he was at Chelsea for a long time.
"There will be a lot of emotion, but we need to forget about all this and go through. We play at home first and want to go to the second leg in the best position we can.
"We need to keep another clean sheet and obviously if we score a few goals that will put us in a strong position."
