It's going to be difficult to choose between Mane and Virgil who's the better player for Liverpool,
Mane is an outstanding striker and Mohamed Salah has an important role in the match.
I must say Roberto Firmino is one of the most underrated players for Liverpool so far this season. He is an invaluable player and his contributions especially in away fixtures has helped Liverpool to pick up vital points on the road and also the Club World Cup.
Not taking anything away from the rest of the players, there are six many stand out performers as is expected in the squad of potential league champions.
