The trio of Diaz, Mane, and Salah were absolutely good attackers for Liverpool however Mane stand out to be the most versatile among the other two players he can play at the flanks and the centre as well as addition of his physical ability and strength is an added advantage, I have not watch Nunez play thus I can't compare him with Mane, however I am very sure Liverpool will miss the contribution of Mane in spearheading their attack especially in crucial matches, there are matches were he singlehandedly broke the strong defence of their opponent.
Liverpool will missed Mane, that's fact for sure. Nunez might find it difficult to work with teammates at first but with as times passes and games, he will fitin their playing style. Perhaps I will Miss Mane, countless number of times, he have saved Liverpool with his dribbling and forcing the all towards his opponents defense and scoring. I give him credits for that and he always turn up when all hope is lost for the reds. I hope Darwin Nunez fitin his shoes and be able to be like him.
It is difficult to choose which is better, Mane or Nunez, Liverpool must have taken a lot of consideration in this regard in determining who will leave and who will help them next season. Nunez is the most prominent name in Liverpool's shopping spree at the moment. Despite all that, I believe Klopp has prepared very well.
