The way Al Nassr lost, was a humiliating one after spending that much on players. They were clearly the better team, and yet they still failed to win. That is the problem they have, even when they are the better team, they lose, and they can't afford to do that much. Ronaldo lost the chance to get one more cup, and it is really not looking good, been years since he got one, they got one on his first year and nothing after that.
Al Nassr coach is too focused on improving their front line that he hasn't thought about recruiting quality defenders to improve their performance in all areas.
It's true that Al Nassr's defense still needs improvement. When Al Ahli attacks, their defensive line is lacking, which ultimately allows Al Ahli to score. In fact, Al Nassr should have brought in more quality defenders during the transfer window. However, I hope that, since the transfer window is still open, there's no harm in bringing in new players to strengthen their defense. If Al Nassr's defense is strong, there's great potential for Al Nassr to win, which will certainly make Al Nassr fans happy.
This failure should help Al Nassr avoid repeating the same mistakes in future matches. Jorge Jesus should have learned from his past experience, but he certainly needs to think hard about developing a strategy to improve Al Nassr's performance in future matches. It's unimaginable if Al Nassr doesn't win the title next season. It's likely that Al Nassr fans and Ronaldo fans will be deeply saddened.
