What is clear is that at this time Mane position is still irreplaceable, Diaz and Nunez are still beyond expectations, that Liverpool still need aggressive players and have attacking instincts as well as being proficient in assists. Look at Nunez performance at the World Cup, just as he can't give his best. It still takes time for Nunez maybe 2 to 3 years he will be greater. But for now Liverpool needs a new player who can collaborate with Moh Salah on the front lines. Because Liverpool's attack structure is still ineffective.
Nunes is still too young, and Klopp brought him into the team with the prospect, he needs more time. But I cant say that Mane was an indispensable player for Liverpool, he did a lot of work and constantly kept the oppositions defense in suspense, but he was not the one that the team was afraid of losing. By the way, in Bavaria, he plays in the same manner.
