most of Egpyt's players play in Egypt outside of Salah and two or three other guys. take Senegal for instance though. just a quick look at their roster shows the got a bunch of players at clubs like Chelsea, Bayern Munich, PSG, AC Milan, Liverpool, etc. all their guys are playing in top level leagues and clubs in Europe. that's a lot of top level talent. most nations outside of Europe would kill to have a roster with that much experience.
