Pep Guardiola believes Ilkay Gundogan is one of the best players in Manchester City's history.

The Spaniard was speaking after Gundogan's display in the 2-0 win over Dinamo Zagreb on Tuesday.

"You cannot believe how good he is," Guardiola said.

"He is an exceptional player. He can play in different positions, with his work ethic. I missed him a lot in our first year here when after a few months an ACL ruled him out for more than six months.

"He is exceptional. He is one of the best signings in this club's history."
