In one factor, Benzema's belief was the thing that made him interested in playing in the Saudi Arabian league. Apart from that, in terms of age and salary, the offer is a second choice for him to play in an easier league due to the aging factor. Also another thing is the existence of the figure of Ronaldo, who is likely for him to be one of the challenges to accept this offer.
Al ittihad are the reigning champions this season and they seem to be continuing to make changes in the squad to increase their strength for next season. With the arrival of kante and Benzema I think they are relatively strong next season even Al nassr will most likely find it difficult to stop Al ittihad in the next season. There are still a lot of players who are likely to join the SPL this season.
It's a very good move for Benzema to join Al Ittihad. Benzema as a player has achieve almost everything in football, especially towards the end of his career. He is a legend for a club as big as Madrid. He's also the player that has won the most trophies with Madrid. That's a pretty big achievement. So taking an offer that gives him a lot of money in a country he would be comfortable in is a wise move. There's also the fact that Al Ittihad has a very good project. They are recruiting the right players and they will still try to get more God players.
It's going to be interesting to see the rivary between Ronaldo and Benzema.
Benzema is joining the league with him being on top level, unlike Ronaldo who was kind of struggling with man utd, Benzema on the other hand was popping off with Real Madrid and we havn't seen a big degrade in his performance, i wonder if he can play the same with different teammates, it will be interesting to say the least.
