I was thinking the same thing as well, concerning how Liverpool will be able to cope without their hit player, I later realized that one thing with nature is that, nature will always fills every gap, might not be exactly the way you want it, but trust me it will be filled up. You can see that the other players have come to the realization that their hit player is not around, so they need to play to leave up to the expectation of the club and so far they've been doing very well. The players you mentioned in their last match, where very brilliant in their pattern of play especially Diogo Jota and Gakpo.
EPL is a top league and the only the strong survives. Liverpool is back to their best, and they will not stop working hard to get three points. Good players are the result of an experienced coach and a balanced team, not some random average coach. I have rather outstanding ideas about Liverpool's statistics. They're a top team and a serious contender for the EPL title. Liverpool does not require the participation of Mohammed Salah because Jurgen Klopp has prepared every step of his squad, taking bold decisions and working ahead of their performance and game fixtures.
