Former Chelsea midfielder Michael Ballack has advised struggling Arsenal star Kai Havertz.
Ballack said that Havertz is too reserved, adding that the Germany international needs a certain robustness.
Havertz has put in unimpressive performances so far at Arsenal since joining the Gunners from Chelsea
The 24-year-old is yet to earn the love of Arsenal fans.
Havertz has scored just once in 12 Premier League appearances for Arsenal this season.
Speaking about his fellow countryman, Ballack told SportBILD (via Sport Witness): “Kai Havertz has outstanding skills. But as already mentioned, he seems a bit too reserved for me.
“You need a certain robustness and mentality, especially abroad, to assert yourself in difficult situations.
“I hope he gets it done. In my opinion, it is still too early for that [an exit]. He should assert himself at Arsenal by all means possible.”
