Cristiano Ronaldo appeared on the front cover of Spanish newspaper AS on Monday with a headline that suggested he’s keen to return to Manchester United.

“Cristiano wants to leave Real Madrid with the player feeling betrayed by unfulfilled promises by Florentino Perez to renew his deal at the LaLiga club,” AS wrote, adding that Ronaldo has expressed a desire to leave to his teammates.

Ronaldo signed a new contract at the Bernabeu worth £365,000-per-week in 2016 but he reportedly feels “tricked” after Madrid president Florentino Perez promised him an improved deal after last season’s Champions League win, which is yet to materialise.

Meanwhile, Marca claim that the Portuguese star is unhappy at earning less than Lionel Messi and Neymar.

Reports of Ronaldo being unhappy in Spain aren’t new and it wouldn’t be a surprise if nothing came of this. Yet a source close to Ronaldo has told ESPN that the report from AS was accurate.

How Man United have reacted to the reports

However, ESPN go on to claim that Man United aren’t convinced that Ronaldo wants to complete a sensational return to Old Trafford.

The Red Devils believe that the 32-year-old is simply trying to frighten Los Blancos into handing him a better deal.

So by the sounds of it, Man United supporters can calm down. Ronaldo isn’t likely to return to the club he spent six seasons at.

Balague: Real would demand £89m for Ronaldo

Sky Sports’ Spanish football expert Guillem Balague believes Ronaldo’s cost was also put the Red Devils off from making a bid for the forward.

“To add to a net annual salary demand of around £44m, Real would also demand around £89m for Ronaldo, which is an almighty expense for a player who would arrive aged 33,” Balague said.

"Here's United's conundrum: the club cannot show a lack of interest if it is confirmed that Ronaldo is on the market. But the huge amount of money his transfer would demand cannot be justified."

With Alexis Sanchez closing in on a move to Man United, it seems Jose Mourinho has already decided on a marquee left winger.
