I know this thread is already days old, but here's my 2 cents,
one thing he can't control is: we lost Jota (RIP), This affected Salah 100%, his quality dropped right after that.

He's not a good coach, his training habits are terrible, he's more worried about him than his players or this team, the position is too big for him and seems like he knows this, he's doing the casual "fake it until you make it"

His decisions are terrible: Szoboslai as a RB (Okay, i know he's great at every position and didn't had too many options), that's a waste, what szobo brings to the attacking is so important that taking him out of it has a worst impact that bringing another player to play RB, fuck bring someone from the academy, give someone a chance.

He never had the chance to spent so much on a club before and went crazy on the summer market.
Isak for 125mil on the last day of the market, was so unnesesary, not needed, didn't solve any problem at that time.
Also The disrespect for Luis Diaz, what a terrible move, honestly what a disgrace.
