Even though so far Liverpool's performance has not been affected without Salah, Salah is a player who can provide better attacking power when Liverpool has difficulty breaking down the opposing team's defense. At the moment it doesn't have much of an impact, but Liverpool really needs Salah's presence in the next few tough matches.
Today Klopp played Diaz, Nunez and Gakp as his attacking trio. I know the match against Fulham is not too tough, but the performance of these three players needs to be reviewed ahead of the two tough matches against Chelsea and Arsenal in early February.
Regarding strength when attacking, it cannot be denied that Salah's presence can make it more difficult for opponents to maintain their defense because Salah has the ability to dribble the ball. However, if Salah cannot play then Liverpool have a number of players who can replace him. This is because several previous matches have proven that, without Salah's presence, they still play much more solidly on the front lines. Of course losing Salah in the team will slightly affect Liverpool's attack, but that doesn't mean they have no choice.
These three players did appear extraordinary against Fulham and they tried to carry out quite neat attacks while near the penalty area. Jurgen Klopp knows what to do even though sometimes there are a number of opportunities that players are not able to maximize and that often happens in football.
