Arsenal midfielder Francis Coquelin is out of Wednesday night’s League Cup game against Spurs, and some Arsenal fans will be concerned by the latest ‘update’ on the player.

The club have a history of not providing great updates on injuries, with fans often left suspecting issues in diagnosis.

The latest examples of this are Danny Welbeck and Jack Wilshere who, after lengthy periods out, only just underwent surgery on a knee issue and a fractured leg respectively.

With Arsenal down to 10 men at Chelsea on Saturday, Wenger withdrew Coquelin at half-time. The midfielder had gone down holding his knee after around 20 minutes and clearly wasn’t ok to continue an has now been rules out of the north London derby.

“His knee is swollen and he is being assessed but we hope it is just a short-term problem,” Wenger said to on Tuesday as he looked ahead to the game.

The lack of information certainly comes as a concern. Clearly he’s out of the game at White Hart Lane, but what about the weekend’s trip to Leicester in the Premier League?

If Coquelin’s injury is more serious than Arsenal are anticipating, the Gunners will have to rely on Mikel Arteta staying fit and Mathieu Flamini not being totally reckless for the time being.
