Arsenal's injury crisis at the back got worse after Arsene Wenger confirmed that Laurent Koscielny will be out of action for at least another month.

The Frenchman had hoped that Koscielny will be available following the upcoming international break, but seems like Wenger will be without his first choice defensive pairing until the new year.

The Gunners boss has revealed that there is no need for surgery in the French defenders case, and does agree that Arsenal are less prone to stupid errors with him in the team.

"He has not started running outside, so you cannot think he will be available in two weeks. He will not be available for three or four weeks," Wenger said, as quoted by the Daily Mail.

"There is no need for surgery. His achilles on the scans are quite good. It's just inflammation. Too much French salami."

"You miss him every time you concede a stupid goal. You think, "Oh, if he was there", but we have conceded some with him as well. Could we have stopped goals without him? I say yes," the French manager added.

Meanwhile, Wenger has given his blessing to Theo Walcott after being selected by Roy Hodgson for England's upcoming matches.

The Arsenal manager believes that his striker needs games to get back to full fitness, and insists that it will take at least two months before the Englishman gets back to his best.

"He will go with England and get what he needs. He will get competitive training and back into games. It takes two months to be back at your best once you're in full training," the Gunners boss explained.

"People think you're back and you play but it's not like that. You lose the sharpness and the speed."

"At the top level, it's a fraction of a second that makes the decisions, and to find the confidence to get away from people," Wenger concluded.
