Oh dear, Ronaldo was substituted just before the end and that with 3 other players at the same time. So no change to bring his quality into the game. That was only to play for time. He make one shot, but that was not really good. Rashford and Sancho will continue to do so well, then Ronaldo can only watch the game.
Manchester United played quite well without Cristiano Ronaldo yesterday, and the coach might prolly want to stick with the team that has earned him his first competitive victory as Manchester United manager, but mind you that Ronaldo is not the kind of player you can keep on the bench for too long, he will express his unhappiness at that openly and will the forcefully seek for an exit.
Having said that, in Manchester United's next game i expect quite some changes to the team that won yesterday, afterall Casemiro is now in the club, and he is definitely going to be their constant defensive midfielder, as for Ronaldo we'd have to wait and see how things develop, there are a couple of days left before the transfer market for this summer shuts, if he doesn't exit the club before then, and he commits to Manchester United, then he can be more focused with the team, and the manager will play him much more regularly.
