Yes, we think such things about Saudi Arabia, but there are still players who return to Europe after Saudi Arabia. There are also some players who see it as a place to earn money. I think Paul Pogba could be one of them. At the end of the two years he spends in Saudi Arabia, he can earn good money and return to Europe. In addition, he will get used to football again during this time.
If his target is to return to the French national team, he must find a club that is ready to guarantee him regular playing time and he must also help himself to return to his best form. Playing in the Arab League would rule out the possibility of him returning to the French national team because the level of competition there is not like in the top 5 European leagues. The January transfer window will open up opportunities for him to get a new club, if he does not get the offer he wants, accepting an offer from an Arab club would be better for him than being unemployed.
