It is difficult for Ronaldo to get his place back in the Manchester United main squad under Ten Hag's tutelage. I don't really know what caused the peak of the problem between the two, but maybe Ten Hag felt unappreciated by his players during his early days in Manchester. Ronaldo is a mainstay striker in any team he plays for, but this season he has not been happy in the team he plays for so the rumors seem to be true.
The media are rumors of a move to Serie A while some others think Ronaldo will join the Potter team (Chelsea). Both teams look good to Ronaldo, but I think in Italy he is better than in the Premier League.
There is a lot of debate regarding Ronaldo's existence at Manchester United at this time, but for sure Manchester United is fine even without his presence. as you said, it is difficult for Ronaldo to get his place back in the first squad.
because after all, he had twice left the bench before the game was over.
although the results of the meeting between Ronaldo and Erik Ten Hag have gone according to plan, and it has been reported that he will return to appear in the Manchester United vs FC Sheriff match.
However, that doesn't make it any special. because after all he must first prove that he is still worthy to play as the team's main starter.
Regarding Chelsea, so far there is no news that confirms that in the winter transfer window Ronaldo will move to Chelsea.
