If we examine it, it means that Al Hilal already knows Neymar's condition but they don't seem to mind it. after all, if it's only a minor injury, maybe Neymar only needs one or two weeks to return to the field to make his debut with his new squad. and in any case, the presence of neymar for Al Hilal will have a positive impact. and as you said, Neymar is not only to strengthen the team but there are other contracts that involve commercial matters.
I think there will be a few problems with him in the future. Brazilian players known to stop playing when they get older or earn too much money. Now he fly in a private jet on a golden throne to Saudi Arabia and his demands for luxury cars, staff, villa with pool, drinks and many more. A person who then also earns 100 million euros per year, why should he bring such an extreme performance?... it will be very easy for him.
But anyway, basically Al Hilal before without Neymar has also had a good performance, so with the presence of Neymar, of course Al Hilal's performance will be even better. Although indeed, I am also not sure Neymar will play with great effort. Because anyway, playing here in the Saudi Pro League, at least it might also be a way for Neymar to no longer have a prolonged injury. Because as far as I realize is, that Neymar no longer has a strong physique, because Neymar is very susceptible to sustained injuries.
