Sure. The top players who are still in the golden age like Lautaro Martinez will prefer to focus on playing in the top leagues in the world. Only those players who are not in their best form anymore who consider to move to Saudi. They focus on earning money, they don't really care about their career anymore.
Realistic with their target on the golden age stay with European teams because they want get national teams called, I don't think if Lutaro Martinez accepted Saudi Pro League teams will get called from Argentina in Copa America and FIFA World Cup. Highest level competition has bigger chance for getting national teams called than play with Saudi Arabia club. Some players have accepted deal with Saudi Pro League teams because want to earn much money and due their age have been over not care about their career any more exactly participants for national teams in FIFA World Cup or EURO.
Why do you doubt Paul Pogba performance at the Juvents club?
Even though Paul Pogba is also an important role at this club and his contribution to Juvents is also very good even though it sometime look inconsistent but in reality he was able to appear solid with other player who were able to bring Juvents to a conference league ticket.
Its not about Paul Pogba performance, but last season he most injured with Juventus and difficult to show his best performance, have rumor with Juventus disqualify from EUFA Conference League after financial fair play cases and its depend with points cut off in domestic league.
