The Rags have gone backwards. The points total last season was the same as the year before, 66 points. Their younger players like Rashford and Martial have just not improved and will probably never make the elite level (Rashford has been ruined by United in my view).
Maguire was good at Leicester but poor at United. Lindelof is championship level and wouldn't get in any other PL team (Lingard the same) Wan Bissaka is good but he has not improved since his good start in the first half of last season, Shaw will never improve because of his lifestyle. Pogba is a total fraud and would not get in any other top six PL side. Bruno is good but, especially when in the Portugal team, he is totally overshadowed by Bernardo Silva.
Greenwood looks great but will be destroyed by the Rags' dinosaur coaches. The club is in turmoil behind the scenes (I know this for a fact)
They will always be able to turn it on for big one-off games, against us and Liverpool, but until the Glazers quit they can only continue to decline. Most sensible matchgoing United fans know this is true. Despite all the banter and bullshit United's hardcore fans know good football when they see it and know that what is on offer now is garbage.
