It's very difficult and sad to see Man United's football game for a few years. I followed Ronaldo's debut at Man United if Scholes, Flecter, Vidic and Ferdinand still play, it was very different. The flow of the ball and their fighting power was fantastic. Today Man United look weak, even the flow of possession looks bad. Even today Man United lose to Man City for game.
Ronaldo is not maximal because he doesn't get the ball well, even I see he has to help defend. The connections between Man United's current players still don't look solid, so they often rush and make unnecessary mistakes.
Coordination in the Man United match is indeed very weak, no matter how expensive and great a player can be, will not be able to win a match alone, it takes very good teamwork to be able to finish the match with a score that matches expectations but in fact we know, the passes given between players just not so good.
