That's what made him want to leave, and look for another team that has a better team quality. But unfortunately it seems that not many clubs are interested in him because of his big salary and old age. Indeed Ten Hag has spoken that he needs Ronaldo, but that does not make Ronaldo believe in the club and stay. In proved he did not participate in the pre-season tournament with Man United.
About Maguire he's just unstable, I don't know. But Man United made him the most expensive defender. Maybe the arrival of the Ten Hag could change his mentality.
With Ronaldo, I think every team can have high expectations. But the problem was that he couldn't do it himself and that was absolutely impossible. Manchester United need reliable players to compete in the standings with other top teams, without that I really believe in the end Ronaldo will not be able to make this team successful.
Ten Hag has to come up with a good plan this season and he also has to take advantage of his ability to bring out the potential that exists in all United players. Ronaldo is still possible to stay, but of course he wants this team to be really serious in the market to get more quality players.
If Ronaldo has no confidence later after being forced to stay at Manchester United, will it be better to work with other teams? I doubt it because of his desire to leave even though Ten Hag has a good plan but Ronaldo's feeling is that he still wants to focus on going out so pre-season is left behind.
But if Ronaldo wants to keep going and as it was rumored to Atletico Madrid whether there will be quality players like Manchester United, I don't think Manchester United is better for now than Atletico.
