Arsenal manager Arsene Wenger has admitted regarding Kim Kallstrom's back injury that he knew his problem before signing him but decided to take a risk.
Kallstrom joined the Gunners on loan from Spartak Moscow despite a test showing his injury which has side lined him for six weeks. While Arsenal two young midfielders Jack Wilshere and Aaron Ramsey are already injured.
The Swedish international who has capped 108 times for his country could recover at the end of this month according to Wenger.
Wenger said that they have to establish the real truth about it. The Swedish player arrived here and Arsenal found that he has a problem with his back.
Wenger further added that first difficult task is to identify a player, of such physique and then they checked him and found that he had a little micro-fracture.
Good news for Arsenal was that Spartak Moscow accepted to share the costs as long as their player is injured, they will pay.
Wenger said that if he had time he would not have signed him, as it was last day of the transfer window they had to sign someone, especially they needed a midfielder as two of their players are currently side lined.
Arsenal were linked with £37 million-rated midfielder Julian Draxler of Schalke, but due to big money they did not make a bid.
Arsenal boss said that they are not against spending, but at the moment they are focused on the current half of the season, they may go for him in the summer.
