The Saudi League will continue to look at European players as long as the addition of foreign players has not been closed. They will continue to try to add European players who have good performance and have a good reputation so they can raise the level of the Saudi League. Ricardo Rodriguez may not be a well-known star player but he is a free agent. So if one of the Saudi League clubs wants him, they don't need to spend a lot of money to recruit the player, they just need to make an offer to the player by giving a high salary so that the player is interested in playing in the Saudi League.
For a 31 year old player of course he has quite a lot of experience but he is not that old so he needs to consider it when making the decision to play in the Saudi League because if he plays in the Saudi League it is likely that his career will not develop like in the European League but if I may suggest if he wants a high salary and his career continues to go well, it would be better if he joined one of the top clubs in the Saudi League like Al Nassr because this club also needs defenders to strengthen their defense.
