Same for Maguire. The performance of Maguire in Manchester United and England are very different. I know Maguire was overbought by Manchester United but his quality is not too bad. Of course I also know his quality is not world class but still usable. It is just Manchester United take all confidence of Maguire away.
About Ronaldo, if he stays, the whole system must work better than in the past season. If their system works better, Ronaldo can play better, score more goals for them.
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.
He had a good first ball passing accuracy was hundred percent.
