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.
Yeah truly Liverpool will eventually filled the gap if Mohammed Salah is no longer with them but however no matter how they feel they can perform well there performance will never be the same as when Salah was with them because the role of Salah in Liverpool is so important that the club may no longer be on the same shape if he is no longer with them, perhaps just like what happened to Manchester City when Kevin de Bruyne had the injury truly they were able to filled the gap but there performance was never the same as when he was there, so the club suffered a lot until he came back and restore the club performance so perhaps that's what may likely happened to Liverpool if Mohammed Salah doesn't play with them.
