Petit believes that Toney and Athletic Club's Nico Williams' should fit Mikel Arteta's system seamlessly and has urged the north London outfit to sign the two strikers.
"I really like Nico Williams and could play up front for Arsenal," he told Genting Casino. "He's very fast, can be an independent goalscorer and combines with teammates. A lot of people said signing Haaland for Man City was a mistake, but the way they control the ball in the opponent's half, they can create lots of chances for him.
"Arsenal need a 20-goals-per-season striker, they currently have a few players who can score 10-15 goals per season, like how Man City used to be. Pep Guardiola changed the system because he knew he needed a striker who could score lots of goals. In Erling Haaland's first season, he broke goal-scoring records and won the Champions League. Mikel Arteta will follow the steps of Guardiola, the way their teams play and a striker would be a cherry on top of the cake. I think Nico Williams or Ivan Toney could score as many goals as Haaland does for Man City at Arsenal"
