On second thought, I think we should consider poor form of Ronaldo as a lack of cooperation with his teammates, not just his age because, in my opinion, Ronaldo's age didn't affect his ability to score goals neither did his age affect his strength and pace on the pitch but I think he's been through a lot lately being a human that has affected his ability to do things they way he ought to do when on the field of play.

Can Ronaldo do well as a Chelsea striker? Yes, he can because he will be welcomed by the fans and the management and the players of Chelsea will love to work with him because just like Manchester City players who will rather not score goals to ensure that Haaland scores a goal in every match Ronaldo will not be under much pressure to get the ball always before he can score goals because his teammates at Chelsea will be doing much of assistance for him to easily score goals.
