Arsenal FC midfielder Tomas Rosicky could miss out the London Derby against Chelsea FC with an ankle injury.

As Arsenal travel to face their London rivals Chelsea today, it will also mark a special occasion for Arsene Wenger, who will be in charge of the Gunners for the 1000th game. And after from the emotions that this milestone will bring, the Frenchman will also have to contain with a few injury concerns ahead of this game.

Aaron Ramsey, who was scheduled to return before the North London Derby, suffered a set-back in his recovery process and Arsene Wenger confirmed last week that the Welsh midfielder is unlikely to return before two more weeks – which means he will also miss out on the big clash against Manchester City at the end of this month along with this London Derby. Theo Walcott, Abou Diaby, Jack Wilshere and Ryo Miyaichi are the other long term injury concerns at the moment, along with Mesut Ozil, who is expected to return before Arsenal’s FA Cup semi-final fixture against Wigan Athletic. Wenger confirmed that Ryo will be out for the rest of the season with a hamstring injury.

“He is out for the season with a bad hamstring injury.” – The Arsenal manager said.

Worryingly for the Gooners, Alex Oxlade-Chamberlain was substituted in the dying moments of Arsenal’s match against Spurs with a minor calf injury, although he is expected to recover in time for this game. Kim Kallstrom has also regained full fitness and could make an appearance on the bench at Stamford Bridge on Saturday after missing out Arsenal’s trip to White Hart Lane. There are also some doubts about the fitness of Nickas Bendtner, who has been in the news for all the wrong reasons recently.

Thomas Rosicky, who scored the winner against Tottenham in the last game, is also a doubt for this fixture and Arsene Wenger has confirmed that the midfielder will undergo a late test to confirm his availability for this game.

“We have a doubt about Rosicky. He will have a test this [Friday] morning on his ankle. Apart from that we have no major problem. That issue will be decided after training, everybody else will be available.” – Wenger added.

With doubts about the fitness of Rosicky, Arsene Wenger is likely to make just one change to the side that won against Tottenham in their last game. Mathieu Flamini, who came on as a substitute in the second half, is expected to start this game in the midfield alongside Mikel Arteta. If Oxlade-Chamberlain regains his fitness in time, which he is expected to do, he will join in attack out wide while Rosicky drops down to the bench.

Expected starting line-up(4-2-3-1): Szczesny (GK); Sagna, Mertesacker, Koscielny, Gibbs; Arteta, Flamini; Oxlade-Chamberlain, Cazorla, Podolski; Giroud
