Former Arsenal striker Kevin Campbell has dismissed doubts around Kai Havertz.
Campbell is adamant Havertz will prove himself in a Gunners shirt.
He said: "There were times when people were calling out Granit Xhaka by saying 'he is rubbish'.
"Next minute, Granit Xhaka is a legend. Why? Because he came through and played in Arteta's system, then did really well in his last season.
Don't tell me a Champions League winner isn't good enough for Arsenal. Nonsense. I am not having it.
You said 'he isn't good enough for Arsenal'. I am saying that Kai Havertz is good enough for Arsenal. Arsenal just haven't been good enough themselves right now. We were top of the league with Kai Havertz in it!"
