While speaking with Genting Casino, Petit said: "One thing I can say about Kai Havertz, is he has never given up. When he arrived at Arsenal, he had criticism from former players, pundits, fans and the media. Mikel Arteta has given him the confidence to play well, even when he was not performing well he would be on the pitch. The pressure on Havertz's shoulders has been taken away, the love and respect from his team-mates have been very important for a player like him, he can be very sensitive.
"At Chelsea, Havertz was clearly affected and he needed a positive environment. His team-mates have the confidence to give him the ball throughout a game, at Chelsea, the team didn't play fluidly so it stopped him getting on the ball. I don’t think he’s been amazing for Arsenal, but he has certainly improved and is playing with confidence now, and that says a lot about Arteta."
