Bojan Krkic will likely miss the rest of the season with a torn ACL.

Bojan picked up the injury in Stoke City's match on Monday in the FA Cup.

Bojan had scored five goals in his last 10 games as he finally delivered on the promise he showed as a prodigy at Barcelona.

The recovery time is likely five to six months at a minimum.

Daniel Sturridge could make his first appearance since August on Tuesday in Liverpool's match against Chelsea in the Capital One Cup.

Sturridge initially picked up a thigh injury in international play and then had a calf injury and a new thigh injury.

If Sturridge doesn't play against Chelsea, he will be available for Saturday's match against West Ham.

“This is a big game but we have to be realistic, we have to be careful,” Rodgers said. “We have shown without him in the last seven, eight weeks that the team is at a good level. If he feels fresh and he feels right to be involved in some part, then we will maybe look at it. But it is a big risk.”

Arsenal have confirmed that Mikel Arteta and Mathieu Debuchy will both be out of their lineup for three months.

Arteta, 32, last played for the Gunners against Borussia Dortmund on Nov. 26, but damaged his calf during the game.

Debuchy dislocated his shoulder against Stoke on Sunday.

"Mathieu had a surgery on his right shoulder following the injury on Sunday," said Arsene Wenger. "It's very unfortunate for Mathieu, it's unbelievable because he's had two surgeries in the same season.

"He just came back, he played seven games and he's out again. I count three months out for Mathieu because contact will be a problem for the shoulder."

Arsenal full-back Mathieu Debuchy is waiting to hear whether he will need to have surgery for a second time this season, after he injured his shoulder in Sunday's 3-0 Premier League win against Stoke.

Debuchy underwent ankle surgery shortly after his arrival at Arsenal from Newcastle during the summer transfer window and has only played six Premier League games since his return to action in mid-November.

Debuchy's latest injury could have an impact on Arsene Wenger's plans in this month's transfer window, with the Gunners manager suggesting previously that he may not need to sign additional players if his entire squad remained fully fit.

Mesut Özil will be available to return from his knee injury this weekend against Stoke.

Özil is returning from the injury earlier than expected.

"He will have training with the squad for the second time [on Friday], so he will certainly be available for selection on Sunday. Will I start him? I haven't decided yet," Arsene Wenger said.

Sergio Agüero will return from his knee injury on Saturday against Everton.

Agüero hasn't played since City's win over Leicester in mid-December.

Agüero has scored 19 goals in 23 games.

Sergio Agüero has returned to training as he works his way back from a knee injury.

Agüero was injured in early December and ruled out for six weeks.

"I wanted you to know I've already started field work," he posted on his official Twitter account on Monday.

"Slowly but surely I'll be back at the right moment."

Adam Lallana will be out for the next month with a thigh injury.

Lallana had begun to increase his production following his £25 million transfer to Liverpool from Southampton.

Lallana scored a brace last Monday against Swansea.
