I tried to find the latest information regarding Neymar, especially as you said that Al Hilal was very angry with Neymar who never played anything else. unfortunately, I didn't get the information I needed. as far as I know, no player wants to suffer a prolonged injury like what happened to Neymar. after all, Neymar was injured while defending his Brazilian national team. so, what happened to Neymat was out of scenario. referring to past news sources, according to Saudi Arabian media, Arriyadiyah, Al Hilal will have Neymar back in its squad next season. However, Al Hilal will remove the Brazilian star from the list to bring in other non-Saudi players. regulations state, that each league team can only have eight foreign players in the squad. it is very clear that Neymar will return next summer. even if there is other news, unfortunately I couldn't find it even though I tried looking for it in several searches. referring to transfermarkt, Neymar is still an Al Hilal player.
In fact, even without Neymar, Al Hilal is still very difficult for Ronaldo and his team Al Nassr to compete with. Al Hilal couldn't use Neymar's services much this season, but they still managed to maintain a safe distance from their rivals, Al Nassr. even though Neymar was absent for a long time, Al Hilal performed well because other stars were able to shine. Mitrovic was the player who shone the most on the front line with his 17 goals, and was only 3 goals behind Ronaldo. apart from that, Yassine Bono, Malcon, Milinkovic Savic, Ruben Neves and one of the local Al Dawsari players, could also be the backbone of the current Al Hilal team squad.
As for Benzema, I don't know exactly what the obstacles are in the Al Ittihad squad. however, it seems that Al Ittihad needs several newcomers, especially those who are able to support Benzema on the front lines. likewise with Al-Ahli, even though they are in 3rd place in the standings, the fact is that Firmino has not been able to show his capacity so far. currently, the Saudi Pro League competition is in a pause phase. and this is good for the teams competing in this League, to carry out evaluations.
Al Hilal got Neymar and Mitrovic because they trust their partnership and they needed both of their strengths to be able to surpass other clubs in the league. It’s unfortunate that Neymar got out due to injury and It’s a pity it turns out to be long termed. Both Benzema and Firmino haven’t been able to get their grounds yet but I think if their respective teams get some good signings from Europe to help on the strikers this will be a boost for the players and the team and make the SPL more competitive.
Now he’ll have to be taken off the squad list so that the Saudi club can bring in a foreign player who’ll strengthen their attack for the 2nd half of the season. It’s so crazy that even without Neymar’s presence Al Nassr haven’t been able to catch up with them yet. Mitrovic has stood out and other European stars also making this team a class team.
