It depends on the form of the players. Mane for example to me has lost form or is losing form compared to two years ago. We don't expect players form to continue for long because they get older as the day goes.
Dude, where have you been? Mane is probably our best player atm. He’s 28, right in the absolute peak of his career. He’s quick, strong, powerful, he has an incredible first touch, his finishing is world class. I don’t know what you’re seeing but I see one of the very best players in the world.
I agree I don't think Mane has lost its form. He is still crucial for Liverpool, you find him in defence then in the attack, fighting for the ball and scoring. In fact his absence in the last game was one of the many reasons LFC was beaten by 7 and scoring only 2 goals... Salah was kind of obliged to go back to defence several times and this will exhaust him for sure, although he managed to score 2 goals.
