Chelsea boss Thomas Tuchel fears his players are "TIRED AND EXHAUSTED" ahead of the new season kickoff.
Chelsea played twice against Udinese in less than 12 hours today and yesterday.
Tuchel said, “It was a pretty long pre-season.
“Tiring and exhausting to be in the US for so long, and having to travel again today under the circumstances is not so easy, pretty demanding.
“After this weekend we prepare for nothing else other than Everton. The season is right in front of the door. There is a lot of positive stuff but we need to improve.
“We are not ready yet. We don't have to be ready yet. We have another week and then it is time to be on the best level. It is always nice when the season arrives.
“We will have this week. There is still some way to go."
