Mikel Arteta has confirmed that Calum Chambers has undergone surgery on what is thought to be an ACL injury.
The centre-back went down during the first half of the 2-1 defeat to Chelsea on Boxing Day and was sent for tests on Monday.
As feared, it appears to be a serious injury and he’ll likely miss the rest of the season. The loss of one of our centre-backs and doubts over the quality of some of the others could spark Arsenal into action now that the transfer window is open.
There has been talk of recalling summer signing William Saliba from his loan at St Etienne and RB Leipzig’s Dayot Upamecano, a reported summer target, is said to be back on our radar.
Asked about Chambers and his plans for the coming month, Arteta said: “We’re going to try to be in the market to see options that can strengthen the team.
“That’s for sure and that’s our obligation, and we’re going to be working on that. My obligation is to give my opinion on the things we can improve.
“Obviously we have some bad injuries, like Calum a few days ago. That’s obviously going to change our plans at the back, but the reality at the moment is that we’re not going to be able to do much.
“I’m more concerned at the moment about getting people back from injuries than I am the signings.
“I want to improve the players I here, get everybody on board and understanding what we’re trying to do. If something extra comes up and we think it’s the right opportunity to improve what we have, let’s do it.”
We wish Calum all the best with his recovery. If it’s confirmed that he’s suffered an ACL injury he’ll at least be able to lean on the experiences of Hector Bellerin and close pal Rob Holding who are both on the mend after suffering the same problem last season.
