Bologna coach Thiago Motta admits he's enjoying working with Joshua Zirkzee.
The Holland striker is being watched by Manchester United, AC Milan and PSG this season.
Motta told Sky Italia: "He has said that his idols are (Zlatan) Ibrahimovic and (Gabriel) Batistuta, who are two great players.
"I see him every day, and I think he reminds me of Ronaldinho, who I played with in Barcelona.
"But I won't compare him to anyone else. He is Joshua, he is special, he enjoys his football and above all he works hard in training."
