Without Ronaldo and Mane, I'm sure Al Nassr will be difficult to compete for the top 5 in SPL. Sure, they were strong but they need stronger now. It is because all big teams in SPL already became stronger, too. Nowadays, Ronaldo and Mane become the mainstay players of this team. I even think Al Nassr too relies on them. This is actually not good, Al Nassr will suddenly be a weak team if Ronaldo and Mane are injured. Or when Ronaldo and Mane can't perform with their best shape. Anyway, winning SPL title isn't easy. Even Ronaldo and Mane joins Al Nassr, they still can't win the title. It is a team game, the whole team must be stronger (not only the attacking line).
However, Ronaldo and Mane has contributed a lot for Al Nassr. It simply can be seen from their stats.
sholynationspWinning is mainstay for most of these players, they're only here to win games and lift trophies based on their topnotch profile in football. Al Nassr can actually survive without the heavy presence of keyplayers but in either ways, their presence is very compulsory and becomes valuable when the appropriate spots is hits. Cristiano Ronaldo and Sadio Mané have contributed heavily to the growth of Al Nassr all these years playing for the club. These are the best representatives of the Knights of Najd, they're outstanding in performance and will always come out ranking top base on their impressive stats. Al Nassr are lucky enough to have these players in their club. Only Ronaldo who's always ambitious, he nets goals and everyone knows how his goals tally have upgraded the level competitive performance of the club.
