The 4-4-1-1 definitely seems to be working, Ronaldo doesn't like a second striker next to him, which they had for a while since Talisca left. Now they know what they are doing and get someone who is like a advance forward type of thing where Felix plays. That is why the problem is looking like gone at the moment and they could be doing much better at the time and we should be expecting them to do a lot better and could get a greater result.
We can't really expect them to be champions right away, there are still so many things to handle and we have so many games, plus anyone can get injured and that would be very important. This is why I think we shouldn't really expect it to be that weird. I think it would be possible for them to still lose, we have to wait and see.
This season, Al Nassr will appear different from last season, with both their strategy and motivation clearly different. Furthermore, Felix's arrival has made Al Nassr's attacks difficult for opponents to contain. Watching Al Nassr's victory over Al Ittihad clearly demonstrates their improved defense and offense.
In that match, Al Nassr lost a player early in the first half, in the 25th minute, but they managed to secure a victory, a remarkable achievement for Al Nassr. The final will be against Al Ahli, a tough opponent, but if they can maintain this form and maintain this formation, they will win the competition and even have a chance to win the SPL trophy this season.
