Herth Berlin boss Pal Dardai has labelled Arsenal loanee Matteo Guendouzi a “rebel” who must “learn like an animal”.
The 21-year-old was pushed out by Mikel Arteta after twice falling out with Mikel Arteta in the space of five months.
Guendouzi first irritated Arteta after a heated bust-up in Dubai, before a red card at Brighton effectively ended their relationship.
The young Frenchman was shipped out on loan to Hertha Berlin, managed by Dardai, who admits controlling Guendouzi’s temper remains a work in progress.
“It’s like puberty for him, he’s kind of a rebel,” Dardai told Bild. “He has to work and learn like an animal.”
The 21-year-old has made 14 starts this season, but was among the substitutes for their defeat by RB Leipzig at the weekend.
Guendouzi did eventually come on with just over 20 minutes remaining, but almost immediately gifted Leipzig their second goal when he surrendered possession inside his own penalty area.
Dardai said: “In training, I always stop these kind of duels because you can’t fall to the ground like this. And, afterwards, he’s mad.”
