Arsenal will be without William Gallas on Saturday for Premiership clash with Wigan Athletic. However, the Gunners are set to be boosted with the return to fitness of Kolo Toure (calf) and Johan Djourou (hip).

Moreover, Wenger also revealed that Emmanuel Eboue could also return after having spent five weeks out with a knee injury, while Abou Diaby is close and Eduardo in need of games to get back his match fitness.

Wenger, whose side stunned Chelsea at the weekend to bounce back in title challenge but lost in the Carling Cup quarter-final to Burnley, saw French defender Gallas picking up a calf problem at Stamford Bridge.

He told Arsenal TV Online: "We certainly lose Gallas for Saturday but we have of course Mikael Silvestre, who will be available.

"We have Kolo Toure available again and he is more suited to playing on the right side [of central defence]. We will see until Saturday how well he is.

"Eboue could be back in the group and Diaby [abdominal strain] could be available from next week onwards. Djourou is fine."

On Croatian striker Eduardo, who has been out since breaking a leg in February, Wenger said: "As soon as possible he will play now. He is joining in full training matches but he needs games now."
