Former Arsenal captain William Gallas wants to see Diego Costa snapped up by the Gunners.
Costa is a free agent after Atletico Madrid agreed to terminate his contract last month.
Wolves and Leeds United are among the teams credited with an interest in the former Chelsea striker - but Gallas has told Arsenal to snap him up.
“Sometimes, when I'm watching Arsenal, they don't show any reaction when they concede, and someone like Costa will shout to the guys 'Wake up!'", Gallas told PlayOJO.
“If he comes to Arsenal, he will cause a lot of problems for defenders."
