Mane's departure from Liverpool will certainly affect the "trio" that Klopp has designed. It's actually quite funny to me because the problem with Mane not renewing his contract at Liverpool is the salary issue
Of course, without Mane, the power of Liverpool attacking will decrease quite a lot. Liverpool attacking rely on Mane and Salah, if they lose one of these players, it will have a big impact. I am surprised that Liverpool won't extend him, they must give him the salary expected by Mane as long as it makes sense. I'm sure Liverpool will regret it if they let Mane leave.
Bayern are ready with the salary that Mane asked for and this is what makes Mane will definitely leave Liverpool
Bayern is a big club, they must have that money to pay Mane's salary. They know that amount of money is not a big problem considering the quality of Mane.
However, I expected that Real Madrid joins the competition for signing Mane. Mane seems to fit playing with Real Madrid attackers (Benzema, Vinicius). Mane can play in some positions (Left-winger, Right-winger, or Second Striker). He can play together with Vinicius and Benzema. This can be a great formation for Real Madrid attacking line.
