You're right, bringing in Nunez will certainly give Al Hilal a sharper front line next season. But I don't think that guarantees Al Hilal will be crowned champions again in the Saudi Arabian League. Currently, Al Hilal's rivals in the Saudi Arabian League appear much stronger. Take Al Ahli, Al Ittihad, and Al Nasr, for example. I believe these three teams are currently performing at Al Hilal's level, and could even be better. So, even if Al Hilal manages to bring in Nunez, they still have to work harder to become champions in the Saudi Arabian League.

Considering how terrible he was when he played there, I think losing that much is nothing, compared to sending him to some European team. If Liverpool tried to find a team around the European teams to sell him to, then they wouldn't get a dime more than 20 million. They got lucky that some Arabian team was willing to pay that much money for him, because he certainly doesn't worth that much.

In any case, Nunez did play there for many years, meaning they did not lose that much per season if you think about it. They now have a lot better players instead, and should be able to score a lot easier. Nunez missed so many goals, their wingers were higher scorers. The really hurtful one for Liverpool will be Diaz who went to Bayern, he was actually good and not terrible like Nunez.
