Rumours that Cristiano Ronaldo was ready to leave Real Madrid shocked the football world last week. 

The Portuguese star is facing allegations of tax fraud in Spain and is reportedly so upset with the claim that he's ready to leave the country altogether.  

Of course, there are only a few destinations he is realistically likely to go. With Madrid asking for around £350 million, according to the Daily Mail, to part with their best player, only a few clubs can afford him.

One of those clubs is Paris Saint-Germain, who have made a number of massive transfers over the last few years, which included bringing the likes of Angel Di Maria and Julian Draxler to France. 

However, if Ronaldo himself had any say in where he goes, there's probably one club he'd like to join above the rest. 

Manchester United.  

The forward had some of the best years of his career there between 2003 and 2009, before moving to Real for a then record transfer fee of £80 million.

The 32-year-old has often teased a return to Old Trafford, suggesting he would at least like to finish his career there. 

But after last week's reports, there would be no better time for the world's best player to return to England.

Fans, of course, have been urging the club to make a move for Madrid's all-time record goalscorer, but it appears that the players have been giving it less thought.

Michael Carrick, who played with Ronaldo during his time in Manchester, has revealed that he's not been thinking too much about the forward's return.

He told Sky Sports, as per Goal: "I haven't really given it too much thought to be honest with you."

"It's not for me to get involved in whether he comes to Manchester United, whether he leaves Madrid or not, that's not my business at this moment in time." 

Although he's not revealing too much, he did give a little tease that may suggest United are open to Ronaldo's return.

"Of course, I was lucky enough to play with him. It was just a joy to work so close to him and see how he plays. We will see how it pans out over the next few weeks and months."
