Pep's private life aside, they fumbled with decision making especially with the players they let go and the players they let stay. Ahead of tue season, players like Kevin De Bruyne, Kovacic, Bernado Silva and Ilkay Gundugan shouldn't have stayed further. I was excited for Gundugan return but there's no way they could keep up with the pace of the premier league competition. Erling Haaland also fumbled as he struggled with converting chances, the exit of Julian Alvarez affected em as he would have brought a lot for them in goal with Erling flopping. All of these affected them.
Yes, you're absolutely right. Personally, I know things with MU have been very tight, but I think what affected them the most was what you said about the Argentinian. He's key, he's very good. In fact, he was the one who caused a lot of controversy in the penalty shootout against Real Madrid, where they touched him twice, I think players like him shouldn't have let him go, Now they can do something about not letting them get relegated.
I don't know what next season will be like, how they can put things together , but it will be a Challenge.
