I am not a Man United fan but its sad to see a once, great team in such freefall decline. There is also some real correlation with the fact that so many of the players who have left or been sold by United in recent years have regained form - Antony for example is back scoring, Sancho looks to be improving with Chelsea and there are several others.
The club is without doubt financially weaker than it ever was, it can no longer pay the massive wages or buy the marquee players and now have to consider selling to be able to buy, i expect Garnacho to be sold this coming summer and maybe Mainoo.
