I don't think Salah will be interested in joining the Saudi Arabian league because he will still love to play professionally in the Premier League rather than going to the Saudi league. Besides he has all the competitions to deal with in the Europe much more than he will benefit from the middle eastern lcub. Arne Slot should not attach sentiments to it. Let whoever deserves a position of play, should be give it to the person. That's the only way he can maximize his performance by the club.
Salah is a player that Arne slot would not make any sentimental attachments to him be because he's very aware of his personality and his importance to the team aswell, one very important thing about the Liverpool team is that they are very determined and it's always seennin their performance and their attitude, I believe that slot Will not be the one to strip them of this form of resilience in them, one big factor that will determine if salah will be willing to stay back and be managed under the coaching of Arne slot would be their relationship and if slot sees Salah in his plan then I believe he would build that relationship with him so he can be able to keep him back and work with him as much nas they could.
