The problem persists for Cristiano Ronaldo. He hasn't won a proper trophy since his departure to Saudi Arabia, and they had built a strong squad this year. I expected them to win the Super Cup, but Cristiano Ronaldo didn't win that one either. The team is contending for the title this year, but this start hasn't been good for them. I think they'll play better in the league over time, and the championship could be theirs in Saudi Arabia this year.
He tried as best as he can, scored goals, made important assists but he could not run too much and contribute too much on proactive defense at his 40s age. Al-Nassr must know this weakness of Cristiano Ronaldo at his very old age and around his career ending and must build up tactics and choose players into their squad for enough support to cover this defense weakness.
Winning titles with Al-Nassr or not, it's not an individual responsibility of Cristiano Ronaldo but it's responsibility of a whole club, from sport director, head coach, and other staffs as well as his teammates in the club.
