AC Milan striker Giampaolo Pazzini feels he's working well with Stephan El Shaarawy.

Pazzini admits the youngster's emergence has surprised him.

"I did not expect this explosion. But mentally, he certainly does not seem like a 20-year-old. He is playing in an impressive manner and always keeps calm.

"But there is still ample room for improvement. He can certainly become a great player."
