Because I think last season was an impossible situation. It was a toxic situation. The squad was horribly coached, horribly balanced, it spiralled, and just as Ralf started improving things and Rashford looked like he was about to get a glimpse of form back, Greenwood gets arrested and we are thrown back into turmoil. That does shit to a squad mentality. Ralf also had an interim title, which is very hard to fully invest in. Half the squad was leaving. They didn't give a feck, hard for the rest who are staying to perform normally. Once we lost to Atletico, the season was done for all. Rashford had a tough summer the year before, put off a surgery for playing in the euros, didn't end up playing at all apart from the penalty miss. He was mentally fecked after that too. And then had surgery to fix his injury. There were COUNTLESS reasons why last season went to shit. Yes, the players are also to blame. Yes, their mentality was shit. Yes the work rate was shit. Yes they gave up. But it's a 1 off season where everything snowballed and went wrong.
If you act based on last season, you have to sell literally everyone and buy an entire new squad. Because what you can say for Rashford applies to everyone. We have some very good players and some shit ones. I'd prioritize keeping those who have shown they can be among our best players. Especially if we have no cover for them. They get another chance based on situation, and because you can't sell them all off, and because of the hope they can get back to a form they showed before last season.
