It's true that Al Hilal has good players in it so that it allows them to achieve maximum results like the last few seasons, Al Hilal always competes tightly in the Saudi League so obviously they don't want to make mistakes that make it difficult for them because clubs like Al Nassr and Al Ittihad will try to maintain their consistency to compete in the Saudi League title race so the competition might be even tighter this season because I see a different quality of Al Nassr unlike before.
I just hope the introduction of this new coach wins them the league because sometimes it's not easy to appoint a new manager and go on to win the title. The look sharp with the new coach but there are competitions, Al Ittihad, Al Nassr and Al Ahli are all looking strong too and ready to challenge for the title. This season will be a very competitive season so it's difficult to predict who will end up winning the title.
One thing i dont like about the Arab transfer is you jsut feel like the sheiks are making slave deals, we all know all the teams are property of some sheiks and we know how they behave and some of them really treat the person badly, no matter what we read in the huge salaries and contract, a lot of players dont like how how they are treated.
I don't know if what you are saying is true and if it is then a lot of players will have rejected their offers and probably look for a way out of there. Recently I haven't heard many complains but the only player I have heard of recently that made a statement about mistreatment is Ivan Toney but I don't think the Arabians are that bad as you say it. Even till now some players join them and I believe more will still join so if they are maltreating players no player will want to join the league.
