Arsenal defender William Gallas will miss this Saturday's clash with Wigan. Gallas picked up a calf injury in the sides 2-1 victory over Chelsea last week and will miss the Emirates encounter with Wigan but Kolo Toure and Mikael Silvestre will fill the void left by the former captain.

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

"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."
