The Manchester United team squad is in good shape right now, so I don't think they'll suffer like they did in the past when they lose to weaker opponents who can't beat them. I also think that when they compete in the Champions League next season, they'll take it much more seriously than they did this year because every team will want to reach the Final stage.
Manchester United were good last season under the new coach, this season they will be better. It is two straight wins for the team now in the pre season games, and although these games are not the perfect games to judge how the team will perform next season, it is a good test that can show the direction of the teams progress and the progress of every player in the team under the manager. Some more players will join Manchester United, Onana the goalkeeper is almost a done deal for them, they will be strong in goal, defense, midfield and attack, they have the players and more are coming.
