The Frenchman was hoping to have Diaby fit and ready for action this month after an ankle injury but the 25-year-old’s comeback has been delayed by a further three weeks after picking up a fresh hamstring problem.
Wenger said: “You won’t see him [Diaby] for a while, the next three weeks.
“I am worried but I was more worried three months ago. His ankle was not good but the surgery went very well then.
‘Now his balance has changed so he has to adjust his muscular strength. He has had two small muscular concerns and if he can get rid of them in the next two to three weeks he will be ready.” he added.
‘It’s a good time to get him right as we have a two-week break after Saturday.’
With Jack Wilshere also on the sidelines the Gunners boss has decided to revive a bid for 24-year-old Granero who is a mere bit part player at the Bernabeu.
It’s understood that Wenger has already dispatched a team over to Spain to thrash out a deal after Real’s La Liga rivals Malaga confirmed their intentions to secure Granero’s signature.
Jose Mourinho is reportedly reluctant to let the Spaniard leave but it’s unlikely he will stand in the midfielder’s way of a move to the Emirates Stadium should a bid of £6 million be submitted.
