Manchester United legend Roy Keane has hailed the quality of Manchester City captain Ilkay Gundogan.

Gundogan’s Manchester City contract expires at the end of the season and the midfielder is attracting interest from Barcelona and Arsenal.

Keane told Sky Sports: “The only issue is probably over the length of contract. City aren’t known for giving out two-or three-year deals. He’s 32 now so that might be the issue.

“Clearly, he will have plenty of options because he’s a world-class player.”
