Neymar situation at Al Hilal is indeed very difficult at the moment,on the one hand, Neymar is a player with extraordinary talent who can have a big impact in terms of commercials, but on the other hand he has no contribution at all to the squad due to his long injury, I think it is better for Al Hillal at this time to make the decision to dump Neymar in the end of the season, to should focus more on players who are more consistent in terms of fitness and the current performance, because such a player can make a more stable and long-term contribution to the team and will also increase the income commercially.
In this case of course we can't blame Neymar, because after all injuries are a risk for footballers and no player wants him, but as you said, before signing a player, Al Hillal should look at the player history in great detail.
In my opinion, Al Hilal will most likely sell Neymar soon, in fact according to news circulating Neymar is rumored to be sold by Al Hilal in the middle of this season (in the winter transfer market). The reason is that currently Neymar can be said to have no hope of being retained by Al Hilal. Especially with his current injury-prone condition, Neymar is certain to be sold by Al Hilal. The reason is, even though commercially, Neymar has had quite a good influence on Al Hilal. However, if for example Neymar continues to suffer injuries like now, I don't think Neymar's big name will have a big impact on Al Hilal's commercial impact. So in this way, Al Hilal will actually experience losses. Therefore, the right step that Al Hilal will definitely take is selling it. Because if Neynar continues to be maintained, I don't think it will go well. Because we can see for ourselves that Neymar's current physical condition is no longer as strong as it used to be. So if Neymar is forced to continue staying at Al Hilal, I think the same thing will happen again (injury). Maybe the best way for Neymar right now is that he should immediately retire from the world of football. Even though it will certainly be very difficult for him, what can you do, with his frequent injuries, it will definitely continue to make his performance decline further. That's why I think retiring at his current age is quite appropriate. Because you can be sure that currently Neymar will not be very interested in other teams, whether in Europe or Asia. Because all football teams now know how Neymar is doing.
