Alisson Becker is a pretty good Liverpool goalkeeper in my opinion and the SPL will get quite good brand value as we see how popular the EPL is this season so players who move to the SPL will be in the spotlight and will increase the value of the SPL itself, Alisson Becker is Liverpool's mainstay goalkeeper and Liverpool will get a lot of money if they sell this goalkeeper, but Liverpool also have to look for a new goalkeeper who is better than the sale of Alisson.
Manchester United had problems when they gave up on De Gea and went for Onana. I think Manchester United owe a big part of this season's nightmare to that. If Liverpool gives up on Alisson without finding a better goalkeeper, they could go through what Manchester United went through. They need to consider some possibilities when choosing to cash in on the sale of Alisson.
What is important now for the Saudi Pro League is to increase its brand value and Alison Becker is a career goalkeeper who can affect the brand value. That's why getting Alison sounds better to them than getting Ortega. I think they are right in their way of thinking. Maybe in a few years they can use the brand quality of the league to transfer the players they want, but the important thing now is to increase the brand of the SPL.
I agree that SPL teams do transfer activity to increase their brand value, but I think focusing on strikers rather than goalkeepers would be better.
