Ilkay Gundogan believes Manchester City teammate Raheem Sterling can become the world's best footabller.
The England forward is in scintillating form this season, having scored 17 goals and provided 11 assists for club and country.
"He is among the five best attacking players in the world, definitely," Gundogan said.
"Just now it's about consistency but he has shown in the last 12 to 18 months that he is able to be that consistent.
"If he can continue like that, he can be on the top."
