There have been few signings under him which went great like Wan Bissaka, Bruno Fernandes, now Ronaldo, Cavani. I think there will always be risk when you buy a player but they have made mistakes when buying players with big tags. I think Jadon Sancho is still adjusting and it will take a time for him. Give him a year at minimum to adjust and make space into team. He is decent but not that special strategist IMO to manage Manchester United.
Next game is very crucial for them as they face Leicester City who have been somewhat a title contender in the PL race for quite some years now. It should be an interesting contest.
They also got too many players on the same positions as well. I mean Ronaldo is a pure striker nowadays, he can't really play at the wings because he is doesn't have that stamina anymore. And we should be understanding of that because he is getting older, even though he is taking care of his body, getting older is no joke, so he is playing like a striker.
However they have so many other players on offense, martial, greenwood, rashford, sancho, bruno, all playing at offense. You can't put all of these players at the front with ronaldo, that makes 6 players at offense and that is impossible. Surerashford is injured and that makes it a little easier, but we are talking about a team filled with star level players who are playing around the same places, and that makes things a lot harder to manage. I understand Ole's situation, I wouldn't be able to get a decent team out there without hurting anyone's feelings neither.
