Liverpool will not be strong not without Mane, but without cooperation and without mutual trust among players in the team managed by Jurgen Klopp.
Mane's move will certainly make a difference on Liverpool's front lines. because Diaz, Mane, and Salah played well up front.
Now Klopp will create a new front line with the arrival of Nunez. I'm sure Liverpool will continue to be strong next season. Liverpool won Nunez. although many other big clubs want him to.
