Chelsea boss Maurizio Sarri has hinted he'll have to rethink his Europa League selection plans.
Sarri admits he has concerns about English football's heavy schedule.
After victory at PAOK, Chelsea face West Ham on Sunday and Sarri said: “In Italy, it is different. In Italy, after this match, we would play for sure on Monday night [not on Sunday, when the Blues visit West Ham ]. In England, we cannot ask this, so we have to play after 64 hours.
“It's not so easy.
“In this moment, maybe it is not a great problem, because we have played only six matches.Maybe in two, three or four months, it will be a problem.
“First of all, I hope to be in the Europa League in three or four months. Maybe then I have to rest many players on Thursdays... five, six, seven at a time."
