Arsenal stun Sunderland but blow as midfielder Cazorla goes under the knife
Arsenal 3-1 Sunderland
Santi Cazorla could be out for up to four months after Arsene Wenger confirmed the midfielder underwent knee surgery on Friday.
The 30-year-old Spain international was injured early in the second half of Arsenal's recent draw at Norwich - but remained on the pitch for the rest of the game.
Wenger admitted afterwards that Cazorla had finished the match "on one leg" and said in his press conference ahead of Saturday's victory over Sunderland that it was a possibility the former Malaga man would be out until March.
It was unclear at that point whether Cazorla would require an operation but, speaking after the 3-1 win over Sam Allardyce's Black Cats, Wenger revealed the player had gone under the knife.
When asked if the club knew if the ligament had ruptured and if surgery was required the Frenchman replied: "We know now. It has happened already. It's not the season. It is at least three months, maybe four."
Wenger said it was the opportunity to begin rehabilitation as soon as possible that had seen Cazorla have the surgery sooner rather than later - having been to see a specialist in Spain last week.
"Santi wanted to have a chance to come back quickly so he didn't want to last too long for 25 opinions and he decided to go straight away," Wenger added.
"The guy said, 'look it's a clear case, it's a rupture of the external knee ligament'. And he said 'Okay, let's do it straight away.'"
With fellow midfielder Francis Coquelin already out with his own knee problem, Wenger's options in the middle of the park are limited.
Club-captain Mikel Arteta is not fit so Mathieu Flamini, Aaron Ramsey and Calum Chambers - who usually plays as a defender - are his only realistic options.
Flamini and Ramsey were paired together against Sunderland with the latter only just back from a hamstring injury.
Ramsey has long-coveted a place in the heart of Wenger's midfield having been forced into a wider role as the manager prefers to partner Cazorla with a more defensively-minded player when he has everyone fit.
The Wales international scored on Saturday and played the whole 90 minutes as he looks to step up his fitness - and he is now determined to make the position his own in the coming weeks.
"I'm still a bit short of fitness and it will take me a few games to get back into it but I'm pleased today with my overall contribution," he said. "I prefer to be back in the middle of the pitch, that is where I feel more comfortable and feel like I play my best football - to grab a goal and get an assist was good for me as well."
The same midfield duo are likely to start Wednesday's crucial Champions League tie against Olympiacos in Greece - with Arsenal needing to win by a two-goal margin, or 3-2 or better, to advance. Ramsey knows he will not be awarded the same licence to get forward in such a game but believes the Gunners can qualify.
When asked about having to put the brakes on when playing centrally, Ramsey said: "It is a bit easier at home because we have the majority of the ball and Flamini normally stays behind so we have that bit of licence.
"But, in the Champions League game, I will have to be a bit more professional in the way we manage the game. Of course we have to choose the right times to do that but we will always create opportunities - just hopefully we can stop them, keep a clean sheet and grab a couple of goals ourselves."
