The Gunners have been inefficient in front of goal at times this season with their goalscorer in chief going through a barren spell.
Diego Costa can still cause ‘a lot of problems for defenders’, says William Gallas as brings up the striker’s profile for Arsenal.
Recognized as one of the most lethal players during his time in England, Costa spent four productive seasons at Chelsea winning two Premier League titles and a FA Cup.
The Brazilian left Atletico Madrid after a mutual agreement to terminate his contract last month and is currently a free agent.
A return to the Premier League is being mooted for the 32-year-old with interest reported from Wolves, who are looking for a replacement for the injured Raul Jimenez.
Gallas believes Arsenal should also be in the race to sign Costa with the Gunners lacking attacking threat this season.
“He would bring character to the squad. He just wants to win games,” the former defender told PlayOJO.
“If his team-mate doesn’t play well, he will shout at them during the game and sometimes I think this is good. 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!’, which can boost the players.
“If he comes to Arsenal, he will cause a lot of problems for defenders but it might also mean Alexandre Lacazette going on the bench again.”
