It's unusual for a 22-year-old player to choose Saudi Arabia. Furthermore, considering that major teams are pursuing him for his career, any player in Sesko's position would prefer to play in Europe. Saudi Arabia has become a place of increasing quality and competition, but it's clear that young players with ambitions won't choose that place for some time to come.
Yup, as much as Arab countries might be paying really well, that could be very much a career dead-end for young players. That's why we most often see that direction being chosen by players close to retirement, as it's quite nice (and profitable) way to end a career.
The reason for that is that the level of the local leagues or AFC Champions League is nowhere near that of European football. This means that a player who has spent years playing say in Saudi Arabia, even if he had great statistics, would be considered a risky sign-up as he would be untested against top-performing European Clubs.
So that career move is often seen as a one-way street. After taking that route, it might be very difficult to return to Europe.
