Given the circumstances, (namely, that he had been recently appointed, and coached, or managed, a team that needed renewal and hadn't been nurtured by him), I would argue that Slot did very well to win the Premier League last season, and I am not so sure that Liverpool fans fully realise this.
This season, it isn't just those Salah spats (and his loss in form), but I would imagine that there also the considerable upset and shock from the sudden, tragic death of Diogo Jota.
This I wholly agree with. Also they didn’t just add players this transfer window, but they also let Luis Diaz and Darwin Nunez depart, and so the effect hasn’t been to create a bigger squad. With Salah’s slump in form, there have been a few cracks in the whole.
