Ronaldo can perform when he is given the spotlight, he will always give his best and try not to disappoint whenever he gets the chance to prove himself. This season, Ronaldo has barely started a game for Manchester United which I think is an indication that the coach doesn't believe in his ablities. Ten Hag gave his reasons to be that Ronaldo is not fit to start which I don't see truth in, I would rather start Ronaldo and take him off in the second half of the game instead of bringing him at the end of the game.
Will you start Ronaldo at the expense of your team losing, he has started Christiano Ronaldo before and he lost, now he has a winning team that have won four consecutive premier League games including beating Liverpool, so why do you want him to change it, like the old Portuguese saying goes " why fix it when is not broken" I don't know the reason why you think the coach doesn't believe in his abilities,I don't think there is a single coach that doesn't believe in Ronaldo abilities in this world, if Ronaldo is not fit is because he refuse to be involved in pre season and that's the reason he is slow to adapt to the demand of the coach.
