If Manchester United wants to make significant changes this season with the player scheme and the way they play this season, the coach and the team as a whole must really care about this. Especially they have to take advantage of the transfer market when it opens again this season and also change the way they play slowly so that there are more significant changes for the team, because what Manchester United needs now is to win in every game that remains this season.
I believe that's the only way they can escape this poor performance they are having, I think after buying some few strong players they should focus on buying some youngsters or develop the ones they have because football this time is mostly for the young because after developing them they will put in all there youthful skills and energy performing on the team because even the Arsenal team they invested more on there youngsters and now the club is reaping the fruit of there hard work.
So in as much as buying more good quality players for Manchester United is important they should also consider the room for youngsters.
