Chelsea manager Maurizio Sarri admits he may need to continue rotating his squad for Europa League games this season.

Eden Hazard, David Luiz and Mateo Kovacic were the only regular starters who missed Thursday night's 1-0 win over PAOK.

But Sarri says he may need increase that number as the season goes on.

He said: "I don't know because for an English team the Europa League is a very difficult competition, because in Italy, if I play in Greece on Thursday I can ask to play on Monday night, but I have to play again in 63 hours, on Sunday morning. I don't know in the future.

"It is not a big problem now because we have played only six matches but in the future it may be a problem. I hope to qualify before the last one or two matches of the group stage."
