I think Liverpool giving out mane to bayern without bringing another top striker like him will actually affect the club, because mane has been a good and competitive striker at the club which was performing great and lifting the club as well. So i don't think mane absent wont affect the team.
Have you followed Liverpool in market transfer movements all this time? Now Liverpool have acquired Darwin Nunez from Benfica for 100 million euros, the arrival of Darwin Nunez is projected to replace Mane, who is rumored to be going to Bayern Munich, so it would be wrong to say if Liverpool let Mane go without a suitable replacement, Darwin Nunez dared bought by Liverpool at a sufficient price and of course there are certain reasons that make klopp dare to pay a high price for the player.
