London - Arsenal midfielder Aaron Ramsey will be unavailable for up to six weeks after suffering a setback in his recovery from a thigh injury, manager Arsene Wenger revealed on Friday.
The 23-year-old Wales international has been one of the London club's star performers this season, but he has not played since December 26 due to the problem.
He returned to full training earlier this week, only to aggravate the injury, which prevented him from making a comeback in Arsenal's 2-2 draw at Southampton on Tuesday.
As a result, and with Arsenal having conceded top spot in the Premier League table to Manchester City, Wenger has revealed that he will try to sign a new midfielder before the January transfer window closes later on Friday.
"Aaron Ramsey will be out for four to six weeks. I count six weeks," Wenger said, in quotes published on Arsenal's official Twitter account.
"We are still trying to bring one body in because of Ramsey's setback and (Mathieu) Flamini's suspension."
