Benzema leaving Ittihad FC is very possible even though there are no rumors about which club he will play for next because it doesn't look like he will retire from football soon, maybe to Ligue 1 to play for his home club like Sergio Ramos did after no longer being at PSG, but if another club in the Saudi Pro League makes an offer, I think he will stay in the Saudi Pro League because he will get a bigger payout than moving to Ligue 1.
The SPL is difficult for these new players; they are unable to perform at their best right now and are unable to comprehend essential top runs in the system. I've seen huge celebrities move to Saudi Arabia, and the most of them have made it out alive, while some keep on struggling. In accordance with records, the SPL will not settle for anything less than the most talented European players. Karim Benzema's form has decreased as he gets older; he is unable to position himself and score goals, and he makes several mistakes on the field.
