Before you start criticizing, look at the lineup Manchester United played. Apart from Rashford and Casemiro, I don’t see who could stand up to Rosenborg. This is a friendly match in which the coach wants to see what the young players are capable of, the result in such matches is of secondary importance. Now, probably after the Euro, the players will receive a short vacation after which preparations for the new season will begin, then it will be possible to evaluate the team’s results.
These friendlies are coupled up with hardwork and determination, it's just a matter of time before we're able to comprehend the club's that are efficient and the ones that are volatile in outstanding results. Manchester United lost to Rosenborg and that's a good sign of improvement? The Red Devils manager, Erik Ten Hag have more work to do because the necessary core sectors have not be reached. Manchester United need to make effort for pressing prominent signings that would entirely changed the system of the club.
