I think it is a bit of a shame that we haven't seen that United team that ended up second in the league became better eventually. Before Ronaldo got there, they ended the season 2nd, and then a year later they had one of the worst seasons of United ever, and I can't put the whole blame on Ronaldo because dude scored as well, so for some reason a team that ended second, added him, he helped, and yet they still ended even worse.
In any case, this team had a very good core, it was already known by looking at 2 years ago, they just needed to be reminded of that and Erik Tan Hag did exactly that, he showed how good they are and what they are capable of doing.
Before now Manchester United have been in a very poor state despite having the greatest player of all time present in the team but just few months after Ronaldo's departure to Saudi squad, Ten Hag has managed to turn things around and even going ahead to win the league cup, I know many people will begin to say Ronaldo was the problem in the team judging from what they have been able to achieve after his departure.
