Football isn't that complicated but ten hag is trying to be way too clever. Let's go a bit simpler. Conceding too many goals? How about you try to solidify it with a more defensive set up? Rocket science, I know. How about let's drop the players who are playing like shit too. Let's play players closer to their actual positions too.
Hojlund
Garnacho Mount Antony
Amrabat casemiro
Dalot Maguire Varane Lindelof
Altay
Anything else is being overly loyal to underperformers, overthinking things, trying to be too clever, not playing those who deserve it, etc.
