Al nassr has so many super stars on its club. I think that the club is not always rely on him at this moment. It's unlikely to happen caused by there was also mane in the club. Nassr is still willing to add new player to its club as soon as possible.
Al ittihad may become the strongest competitor if salah will be coming there. Even though benzema has been giving awareness for him not to join but it's likely salah will agree. He will become the most expensive player in the world.
You missed something that Al Hilal is now at the top of the standings, they also have quite a lot of stars. There is Aleksandar Mitovic, although he is not as famous as other top players, this player has scored four goals in his three matches with Al Hilal. apart from that, they have Malcom and also Neymar. these two players, can rotate each other. Apart from that, there are several other players who are quite established and really understand this competition. for example, Michael and also several local players who have qualities above the average for local players from other teams.
If Al Nassr targets to win this competition trophy, they must overthrow their toughest rivals. Apart from that, Al Ittìhad as defending champions will defend their title. rumor has it, they want Salah to join and deepen their team squad. If Mo Salah is finally brought from Liverpool, Al Ittihad will increasingly become a very competitive team. Thus, it is not an easy matter for Ronaldo and his colleagues to win this trophy easily, especially now that they are 4 points behind the top of the standings.
if Al Nassr achieves minor results, then their rivals will widen the gap in points. So, like it or not, Luis Carlo has to bring his team to win game after game. thus, they will reduce the points gap from the top spot. that way, the competition will be more exciting.
