The report claims Ronaldo could move to England if the Red Devils meet Real's £80million asking price.
Super agent Jorge Mendes, who takes care of business for both Ronaldo and Mourinho, could engineer a deal between both parties.
The Portuguese international will take centre stage on Saturday night when Real take on rivals Atletico Madrid in the Champions League final.
But there are concerns over the 31-year-old's fitness after he missed a training session last week and suffered a knock yesterday - but he insists he's fit enough to play.
“I had a little scare... but in a couple of days I will be fine," Ronaldo said.
“I’ve had a little problem, but having been the most used player this season that is normal.
“I think it’s the season where I’ve played the most minutes, and taking out this problem from training I am at my best.”
