Does yet another knee injury prove Arsenal still have a problem?

The Arsenal and England right back Carl Jenkinson may not have been playing for the Gunners this season. In fact he has spent the last 18 months across London with our Premier League rivals West Ham. But he has been with Arsenal since the summer of 2011 and so has spent a lot of time under the coaching and training methods of Arsene Wenger and the Arsenal back room staff.

Which is why I think we should be worried about the Sky Sports report that explains that the 23-year old has been brought back to his parent club for medical treatment on the knee injury that looks likely to finish his season. The injury was picked up during a seemingly innocuous challenge with the Man City striker Sergio Aguero and it was originally thought to be just a minor problem.

How many times have we heard that about Arsenal players, only for them to then be out of action for a long time? That is not the only reason for Arsenal fans to be concerned because a massive amount of our injury problems have been knee problems.

Even now three of the four players on the Arsenal injury list are there because of their knees. We have heard fitness experts suggest that these sort of injuries can be caused or made more likely through training methods, so does this latest incident prove that the club still has an underlying problem?
