Antonio Conte admits he has no idea when Alvaro Morata will be fit - and fears he could miss the rest of the season.

Chelsea striker Morata has been out for nearly a month with a back injury and Conte claimed that his absence has had a big impact on their poor run of form.

Morata has trained this week but has already been ruled out for West Brom on Monday because of the long-running back problem.

Chelsea boss Conte said: “We are talking a lot about bad results, but sometimes we forget we are facing a serious situation.

"Players like Morata, for us, are very important and have been missing for a long period of time.

“I don't know how long he will be out. We are struggling a lot to find a solution to solve the pain in his back.

"If you ask me whether he needs a day, a month or the rest of the season, I don't know. I don't know. For this reason, I'm a bit worried. You know very well the importance of the player.”

Conte did hint that Olivier Giroud could start against West Brom on Monday night. Conte added: “Giroud has trained and will be in contention.”
