It is undeniable that Manchester United is the first place that made his name big after Sir Alex brought him to Old Trafford after a pre-season match against Sporting. But returning to Manchester United was also not a good story for him, as happened before, he even left when the atmosphere was not good. This time will join for the 3rd time? I personally say he should choose another place than Manchester United, his age is no longer possible to play at Manchester United. And also Manchester United must get fresher players.
In my opinion, it's a rumor that will never come true, so just ignore it.
Ronaldo will not return to Manchester United just to prove that Ten Hag is a coach who has made mistakes in his career. He didn't have a great season with Ten Hag and that can't be denied, but Ronaldo is a great player. In the SPL, Ronaldo shone and he seemed happy to be there instead of returning to Europe.
From what I understand about sports, when there is a "rumour" going around, it could very well be true of course, but most of the time it's just agents telling what's going on to Fabrizio, and just testing the waters. If the comments on it is great then they consider it for real, if the comments are bad then they back out.
So to give example here, they just published a rumour about Ronaldo going back to United yet again, and they wanted to test how fans would see it, in this case if fans are in favour of it then they would actually take Ronaldo to United, but if the fans are not happy about it then we could see Ronaldo staying at Saudi league. By the looks of it we are seeing them not really be happy about the potential of Ronaldo coming back and that is why I believe that this may not happen at all.
