Chelsea wing-back Ben Chilwell suffered an ACL injury against Juventus in the Champions League on Wednesday, head coach Thomas Tuchel has confirmed.
Chilwell was forced off with a knee problem following a coming together with Juventus midfielder Adrien Rabiot in the second half of Chelsea's 4-0 win at Stamford Bridge.
Tuchel admitted after the game that he was unsure whether he would be able to face Manchester United on Sunday, live on Sky Sports, but on Friday revealed the injury was more serious.

"Ben has a partial injury of his ACL and the decision is to treat it conservatively," said Tuchel. "And the next six weeks will tell the story actually if he makes it and if he will be fully available after the six weeks, or if he needs surgery after that.
"Right now I only care about the six weeks, we are very positive because the first redaction of his body is very positive.
Very frustrating picking up an injury in a moment like this when I am really enjoying my football and playing in this team. I will do everything I can to get back on the pitch as soon as possible. Thank you for all the messages of support. ❤️ pic.twitter.com/JYvd2Vs13C— Ben Chilwell (@BenChilwell) November 26, 2021
"Hopefully it stays like this so now the full focus of everybody is on the next six weeks, to try to bring him back to play.
"It's a very responsible decision, so there's no rush, no pressure."
Reflecting on the injury setback later on Friday, Chilwell tweeted: "Very frustrating picking up an injury in a moment like this when I am really enjoying my football and playing in this team.
"I will do everything I can to get back on the pitch as soon as possible. Thank you for all the messages of support."
Marcos Alonso will now step into the frontline as Chelsea's premier fit left wing-back, but the Blues also have the likes of Callum Hudson-Odoi who has impressed in the deeper wide berths.
Chelsea's German boss Tuchel revealed Chilwell is maintaining an upbeat outlook despite his injury blow, given initial physical reactions to the problem have been positive.
"We need to talk about it again in six weeks, maybe we don't need to talk about it because everything is fine," said Tuchel. "This is the best case, it does not help if we start now speaking about worst cases, because there is also a best-case scenario.
"The next weeks will determine the direction. Right now, this is what we have. There is never a good moment for big injuries, and injuries in general.
"This for him personally is a very bad moment, because he was so good and so full of confidence, he was a huge part of our performances and victories in recent weeks. It's a shame and very sad.
"But he's actually in the moment very positive, because his body reacted very positively to the first treatments and to the injury.
"So after a while you have to refocus and focus on the positive things. And that's now the next weeks to do everything possible he can to come back and help us on the pitch."
Premier League leaders Chelsea will host Manchester United at Stamford Bridge on Sunday, with N'Golo Kante likely to miss out through a minor knee issue.
France midfielder Kante could require just one week to be back to fitness.
"N'Golo twisted his knee a little bit against Juventus, and feels quite better since the game but seems like he will be out for some days," said Tuchel. "It's a matter of days, one week maybe.
"We still have a little bit of hopes but it will be almost a miracle if he makes it, so we think about a week."
Romelu Lukaku has shaken off a niggling ankle problem, but the Belgium striker remains short of match sharpness.
"Romelu is in training, and if you ask the player he will say 'yes I can start for sure'," said Tuchel. "But there is a bit of difference between ready for training and ready for games, then there's a difference between being ready for games and ready for Premier League games.
"The possibility that he starts is not very high, because we can't be sure what happens in between matches.
"We have to find the balance between giving him minutes and being absolutely competitive with the guys who start."
