Better stamina than Ronaldo? I would bet if they had to pass a fitness test that most of the time Ronaldo would be the one who comes out on top. I think even the toughest haters of Ronaldo have to admit that his physical condition is insane for a guy at the age of 38. His stamina is not to be confused with his top speed although I think that he would still be faster than Mane as well. But his stamina is probably better than 90% of the players in
I compare with Mane not with other SPL players who have been at that level for a number of years. If you believe by looking at his performance in the match you should be observant. At the moment Ronaldo doesn't even dribble much, his movements look more passive. Very different from Mane who tries a lot to open up space and dribble. Maybe this is why you think he's still pretty good. Age will definitely make the player's strength go down, it has already been seen in Ronaldo. Therefore, now Ronaldo's style of play is simpler, he tries to be a finisher, not a maker.
