Former Manchester City defender Nedum Onuoha believes his old club are keen on Aston Villa midfielder Jack Grealish.
Recent reports have suggested City boss Pep Guardiola is a keen admirer of Grealish, while midfielder Kevin De Bruyne was said to have been impressed by the Villa No.10's performance for England against Belgium.
Onuoha, appearing on Soccer AM, said Grealish would improve United but hinted at a potential City move for him.
"To be honest, I have heard he might go to City," said Onuoha, who made 116 appearances for the Etihad club after coming through the academy.
"He is a top player, Jack Grealish is a top player, and United might benefit from having a player like that in that building."
