Rio Ferdinand has urged Manchester United to sort out the uncertainty surrounding Cristiano Ronaldo's future.

The 37-year-old has been linked with a move away this summer after indicating that he wishes to play for a club that will compete in the Champions League this season.

After missing United's pre-season tour to Thailand and Australia due to family reasons, Ronaldo returned to training last week.

Despite featuring in Sunday's friendly against Rayo Vallecano, the Portugal international is still looking for a way out of Old Trafford this summer.

With Ronaldo's future still uncertain, former United defender Rio Ferdinand has warned against the situation dragging on.

Speaking to The Mirror, Ferdinand said: "As players, you just want the situation ironed out and sorted out immediately. You don't want it lingering on and dragging on, I think Harry Kane had that with Spurs last year.

"But I think the reasons are different. Cristiano, there's been issues behind-the-scenes with his family and health and stuff like that. You have to take that into consideration."

Ferdinand also stated: "But if the reports are true - that he's looking to move and what not - then you kind of want the club to nail that down so there isn't a hangover going into the season."

The former England international also commented on United's pre-season: "I don't really look at results in pre-season. I've played far too many games in pre-season and lost and it had no reflection on the coming season.

"I think it's more about the noises I'm hearing out of the training ground from the players, listening to individuals talk really positively - there seems to be a bit of a spring in their step now."

Man United will begin their Premier League campaign with a home match against Brighton & Hove Albion on Sunday.
