Gunners are currently in the run for the Premier League title, with Manchester City being their main rivals on the way.
Mikel Arteta’s side will be looking to improve the squad for the next season in order to have even more compatible squad and fight in the domestic league and at the European level.
Merson believes Arsenal need to get a new attacker and suggests that Brentford star Ivan Toney could be a good match for the team.
“I don’t see too much difference between him and [Gabriel] Jesus; I don’t, but if I was Arsenal, I would take him,” the pundit said.
