It hasn’t been the greatest season for Real Madrid.After losing four times in the first half of their league campaign, Zinedine Zidane’s side have fallen 19 points behind Barcelona - meaning they’re closer to the relegation zone than their El Clasico rivals in terms of points.And the form of Cristiano Ronaldo hasn’t helped matters.The Portuguese superstar has scored just four goals in 14 league games this campaign - a return which is unrecognisable from previous years.Therefore, it perhaps isn’t too surprising to see some rumours surrounding his future at the Bernabeu.And, on Monday, a report emerged in Spanish outlet AS.They claim that the five-time Ballon d’Or winner has decided he wants to leave Madrid as he “feels cheated by the promises not fulfilled by Florentino Perez.”They claim that, despite promising a lucrative contract renewal, they haven’t offered him one.After his match-winning performance in the Champions League final against Juventus last season, Ronaldo insisted he wanting to retire at Madrid but claimed that decision wasn't up to him."I want to continue in Madrid if possible," he said after the 4-1 victory in Cardiff."If possible, I would like to retire in Madrid. But it does not depend on me, I'm not the boss in the club."

THE CLUB RONALDO WANTS TO JOIN

But the most interesting aspect of the report isn’t that Ronaldo has decided he want to leave. It’s the club he has his heart set on joining in the summer.

AS go on to claim that his priority is to return to Manchester United as he considers it the “ideal setting” to continue his career. Ronaldo has even told his Madrid teammates of his wish, while the Red Devils are fully aware of his desire to return.

AS even included the story on their front cover on Monday.

Whether Jose Mourinho and Ed Woodward can strike a deal for the 32-year-old remains to be seen. United look set to sign Alexis Sanchez from Arsenal in January so it could be argued that they don’t need Cristiano.

But with Cristiano so desperate for a sensational return, United need to decide if they want to pursue the forward in the summer.

One thing is for sure, Ronaldo has made up his mind.
