Manchester City midfielder Alex Robertson is on Cardiff City's radar as they seek to strengthen their squad.

Robertson, 21, had a successful loan spell at promoted Portsmouth in League One last season.

The Australia international is entering the last year of his contract at the Etihad Stadium.

Cardiff manager Erol Bulut is looking to bolster his midfield.

That need is more acute as the club are happy to listen to offers for Ryan Wintle who has not travelled on the Bluebirds' tour of Austria.

Dundee-born Robertson moved to his father Mark's native Australia, at the age of four and then joined Manchester City at under-15 level following a spell with Manchester United.

Robertson had a brief loan at Ross County in Scotland, before impressing at Portsmouth as he made 23 league appearances and scored once before a hamstring injury that required surgery and ended his season in January.

Portsmouth are understood to be keen on a reunion with Robertson after their return to the Championship.
