The Togo forward believes his former team lack a real physical presence on the pitch and this is why they struggle to cope when they are put under pressure.
He said: "Arsenal are a good team when they have the ball. When they don't, they are not that good. When you put them under pressure, they can't handle it.
They don't have a lot of physical presence. Apart from Flamini, I don't see anyone who puts themselves into a proper battle.
"Rosicky is not that type of player, Cazorla is not the type of player who defends. Arteta is trying to do it, but that's not his job.
"They don't have anybody who can say, 'If I have to kick, I will kick. If we have to fight, I will put myself at the front of it.
"That's how we have to play. Push them and force them to make errors."
