Chelsea star Kai Havertz has been urged to stop being a nice guy and be more aggressive if he wants to be a success at Chelsea.

This is the view of former Chelsea defender Frank Leboeuf, who believes the German attacker has quality but lacks aggression.

“Kai Havertz is a very nice guy, a real gentleman,” Leboeuf told Si & Dan Talk Chelsea.

“But I want him to be a warrior, I want him to be upset; I like when he’s upset and he shows his character.

“But I want him to finish the job and be harder than he is. We don’t have that, he’s not a striker either, he needs a centre-forward next to him.”
