Athletic says the following:
"Paying him ?350,000 per week for the next three years up to his 33rd birthday represents an outlay of nearly ?55 million. It?s a big commitment but small fry financially compared to the cost of trying to adequately replace him.
Salah was eager to commit to a host of performance-related bonuses linked to lofty goal and assist targets ? a clear sign of his confidence. If they are triggered he could earn closer to ?400,000 per week
"
So it's clear that the base is 350k GBP Per week (Gross), which can rise to 400k GBP if he hits crazy numbers in G+A
That's roughly 10 m GBP ( 11.6m Euros) potentially rising to 11.4 m GBP (13.2m Euros) NET per year.
Crazy for Liverpool, not so much for the rest of the top clubs.
They are not gonna give same money to any other member of their squad, and to Salah himself after '25 when this contract will expire (only 3 years)
