When asked which striker Arsenal should sign, Gallas told Prime Casino: "I think Victor Osimhen would be the man I would try and sign. He’s been performing well for Galatasaray, obviously on loan from Napoli, and he’s only going to be there for a season. He’s a good player. Maybe not the player, but maybe he can score 20 a season. But if he doesn’t, he gives you movement, he gives space for the second forward to exploit and score goals. He takes the focus of defenders, so he could play with Kai Havertz or another striker. He will be a little bit more free and then he can score goals for the club. So that's why a striker like him would be good for Arsenal. I was talking about this many years ago. He was too good, I think, to go to Galatasaray. I'm still saying the same thing. I know the club’s fans are going to be on my back again. Is he too much of a big player for Arteta? Maybe Mikel Arteta doesn't have the personality to manage players like Osimhen or to deal with players with personality. Big managers like Klopp, Guardiola, Ancelotti, Mourinho and Ferguson. Even Arsene, he had the personality of being our friend, but he knew how to speak to players. You have to know how to speak to your players. It doesn't mean you're going to have arguments. You have to know how to deal with them, that’s all."
