But the Scotish Sun have cited a report from Italian newspaper Libero that insists Ronaldo will return to Old Trafford next season. This continues from claims in his home county that the 33-year-old has already decided to leave the Spanish capital this summer.
Ronaldo first threw his Real Madrid future into question immediately after their Champions League final win over Liverpool.
Ronaldo has remained coy over his future following those comments but many expect that the Portuguese star will shed further light on the next step in his career after the World Cup.
United fans would likely love the prospect of Ronaldo returning to the club this summer as they look to close the gap on Manchester City, although a potential return could be the catalyst for the end of Anthony Martial's career at Old Trafford.
