If Ronaldo is coming back to the premier League and is being rumoured to join Newcastle United, that I think is a welcome development.
But the reason why I had to bring up issues Ronaldo had with ten hag is because, even after this two years, Ronaldo is still performing brilliantly, if ten hag had managed the situation well as a coach, I believe the youngsters Manchester United have now would have been blinded with Ronaldo's experience to improve the teams performance. United is not doing well at the moment, their high level of inconsistency is too much to even place a bet in favour of them to win a match
I understand your point but Ten Hag might have another reason why he did it, and as far as I know other players at Manchester United don't really like Ronaldo either they thought he was too selfish or maybe they are not able to compete with Ronaldo lol. I say Manchester performed better based on the results of its last match of the 7 wins, 4 of them came in the last 5 matches, previously they were in 10th position and now they are in 6th position meaning there is a drastic improvement based on performance and results, if Manchester United is consistent with these results then I wouldn't be surprised if they overtake Tottenham.

In the next match Manchester will face Everton, this is their chance to get 3 more points I mean it shouldn't be difficult to beat Everton even though they are playing away, but Manchester United is still very confident after the last 2 wins, on the other hand Aston Villa and Tottenham are fighting each other next week meaning one of them will drop points and Manchester United can take advantage of that.
