It was more about the wage; Liverpool's offer was far below his demand; if Liverpool had met his demand, he would have signed the contract and the new challenge BS would not have existed. On a related note, he was not feeling the love because everything was about Salah. But, in reality, it was all about the money.
I think he could have paid him whatever he wanted at Liverpool. They gave 100 M€ to Darwin Nunez. If they could pay that high, they could give him the salary he wanted. Sadio Mane was playing great. Because, along with Salah, they were Liverpool's biggest weapons. I want to say that I am very surprised about this. I thought Liverpool would try very hard to keep Sadio Mane in the team.
That was Nunez's release clause, which is quite different from the Mane story, and Nunez is still young and a rising star in Europe. Darwin Nunez will earn £140,000 per week.
