Actually Liverpool is well rounded club, the unique from the strikers in Liverpool is the winger position has a sense to score a goal, not helping the center forward for finishing. This is why Salah really need a center forward who can help him to score, if all of the strikers are finisher, it will much harder to make a goal since there's no player can give a good short and long pass.
Salah can play on center forward, but he's way better when he play on right winger position.
Mohammed Salah has always been very suitable to be on the right wing and that makes it easier to dribble balls into the opponent's defense, he has enough speed to compete with opposing defenders. Jurgen Klopp still seems confident in the performance of Darwin Nunez as a center striker, even though we know he hasn't been able to do much for Liverpool even in this world cup competition he played very badly for Uruguay.
