Age did not only affect Ronaldo's performance in terms of football playing it also affected his behaviour. When you see Ronaldo you will discover that he is always sad, either he is sad with himself or he is sad with his fellow players or he is sad with his coach or he is sad with fans or he is sad with opposition players .
He is no longer comfortable, I don't know what to say about Ronaldo but he should consider himself as a legend and try to be less off the media
With Ronaldo's current age he is still playing with good performance because he always keeps his body strong but Ronaldo doesn't have to force it because sometimes Ronaldo's efforts to get the ball and score goals are sometimes constrained like what happened at Manchester United, and finally he left the club and it is likely that many would want to have Ronaldo as a football legend with an old age but still able to compete well.
