The polish striker has settled in Seria A instantly, and also creates an impact in the champions league against Dynamo Kiev.
The Spanish goalkeeper Pepe Reina feels that dynamic feature within himself to follow the footsteps of Robert Lewandowski.
The 22 year old striker has joined Napoli from Ajex in this summer, for 32 million, to fill the gap left by Gonzalo Higuain, and he has made a impressive start his new life at Stadio San Paolo.
Milik netted twice against AC Milan, where they beat AC Milan by 4-2, in the Seria A match, and he also scores twice against Bologna in the Seria A, and against Dynamo Kiev in the champions league.
"Lewy has more experience than Milik and has won more trophies, but Arek has a great future ahead of him," Reina told the official UEFA website.
"I am convinced he will soon be a key player for Napoli. It will not be easy for him to reach Lewandowski's level, but he does have the potential to do just that.
"There are six or seven years between them, so I think Arek will have to be patient. When he has matured more and is 25 or 26 years old, we will see what he is capable of.
"But I have no doubt that he will do well at Napoli and will continue to grow both as a player and a person. I am sure he will have a fantastic career."
