Bayern Munich teenage sensation Joshua Zirkzee has been labelled a talented but arrogant player by his former youth team coach at Rotterdam based Spartaan '20, Ricardo Willemse.

The Dutch-Nigeria striker spent three years (2010-2013) at Spartaan'20 under the tutelage of Willemse before moving to ADO Den Haag.

"I am not the founder, but I have certainly helped somewhere in his career," Willemse said to Voetbal Primeur.

He continued : " "Joshua had two faces. He was a very talented boy, but with a certain attitude that I didn't always like. I just thought: act normal.

"He was not annoying, but arrogant. Scoring and not celebrating, because he thought: that is quite normal for me. But off the field, he was a super fun and social boy, who was very nice with his teammates."
