Sporting Lisbon chief makes admission about Cristiano Ronaldo's Manchester United future

Sporting Lisbon sporting director Hugo Viana does not believe it will be "possible" for Manchester United star Cristiano Ronaldo to return to his boyhood club.

Speculation concerning the Portuguese star's future has been a hot topic over the last 24 hours, following reports that new Chelsea owner Todd Boehly had met Jorge Mendes and discussed the prospect of luring Ronaldo to Stamford Bridge. However, United are adamant that he will not be sold this summer and he is set to play a key part in Erik ten Hag's plans this forthcoming season.

Viana admitted the landscape of United is starting to change for the better, for Ronaldo as well as the team.

"It's time for Man United to stabilise, create a good spirit inside of the club and from what I can see from outside, even though I don't know for sure, it's something that has not happened until now, Viana told Sky Sports. "But there is always time to rebuild everything, and with players like Cristiano there is a player that scores 20-25 goals per season.

"It is really important to haver that kind of player in your team."
