Marko Arnautovic's management are thrilled after seeing the young Austrian taste action in Inter Milan's 4-3 victory over Siena on Saturday.

The on-loan FC Twente striker was handed a shock appearance by Inter coach Jose Mourinho to give himself hope of staying with the Serie A champs.

Arnautovic's agent, Peter Baars, told TMW: "We hope to continue like this. He needs to become familiar with Italian football, all the young players need to play to gain more confidence and if his confidence grows he can be great value for Inter.

"In Italy, however, it is difficult for all players, because it's a different game and you must change many things.

"Mourinho said that Marko has the mentality of a child? I am 52 years old and when I compare that with a young 20 year-old, sometimes he does seem a child. Mourinho is one of the best coaches in the world, a great professional. Inter are fighting for the Champions League and so Mourinho has less time to educate 'children'."
