No, its about giving them a chance to prove themselves. Lindelof has hardly played and when he does everyone moans about him. And why even play him at all if hes not good enough.
Sorry, but blaming Ed for Mourinho is ridiculous, he is one of the most successful managers ever. His CV is top of the pile. This contradicts your whole post about signing better players as we signed one of the best, most successful managers, better than Moyes and Van Gaal. manager that didn't work out. Then finished in the top 4 and won trophies. Saying there is no coherent strategy makes no sense
And bar the first one, which was more down to Gill, this is the only window he has not delivered on every player. Go back to under SAF reign, he managed with not signing record fees every summer.
Losing to Brighton is down to the players and manager, blaming the board is some Liverpool, Hicks and Gillett type stuff.
