With the 36-year-old's future at Juventus appearing uncertain, rumours in Spain suggest that manager Carlo Ancelotti's return to Los Blancos has piqued the forward's interest.

According to AS, Ronaldo would strongly consider going back to the 13-time UEFA Champions League winners in this window if he was approached, though Real are believed to be waiting on Kylian Mbappe before making a decision.

The Frenchman has reportedly told Paris Saint-Germain that he will not extend his contract beyond 2022 and could be open to joining the Spanish giants ahead of the coming campaign.

What is Ronaldo’s legacy in Spain?

Ronaldo, a five-time Ballon d’Or winner, spent nine years at Real between 2009 and 2018, after he joined the club from Manchester United. To this day, he holds several different records at the club, a few of which he could extend should he make a sensational return over the coming weeks.

In the gallery above, we have specifically looked at goalscoring records Ronaldo achieved in Spain, being that he is widely considered among the greatest goalscorers of all time. While most of them will be incredibly difficult to match or beat, one that might be hardest to surpass is Ronaldo’s record of 105 Champions League goals for the Madrid-based side.

How would he be remembered at Juventus?

Ronaldo, as expected, has continued his exploits in front of goal in Italy, having struck 101 times in 133 matches, but many critics have suggested his move to Juve cannot be considered a successful one in terms of what it has brought the club.

The forward was seemingly lured to the Bianconeri because of his Champions League pedigree, though the team has not gone any further in the competition with Ronaldo than they did without the Portugal captain.

That, however, might be through no fault of his own, with the ex-Sporting Lisbon academy starlet still as deadly in front of goal as ever.
