This is what Cristiano Ronaldo said recently...
In my opinion, Ronaldo is being hypocritical, since in 2013 he received the Golden Ball and did not win the Champions League, since Bayern won this tournament that year. And if he really believes that a player who has not won the Champions League does not have the right to receive the Golden Ball, then he should return the Golden Ball, which he received in 2013.
Ronaldo may be saying this after discovering that Champions League competition is difficult maybe that's the angle he is seeing thiings now as he is no longer in the league that plays the champions League, also he can not return what he won many years ago not even when the players that should be given the award if we are following what Ronaldo said is no longer in Bayern Munich. The Golden ball should be given to the player that won many major trophies like the league title, the champions League and any other major trophy but the player should have shown individual performance like good goal record for the season and a total all round good performance that could be how best to determine the qualified player to win the award.
I would also not be tied to the obligatory victory in the Champions League to give this award, because there are so many characteristics that this is only one of them. It turns out that according to Cristiano, if a player has won many other tournaments during the year, has shown high usefulness on the field, such as scoring goals and giving assists, then he should not be considered the best footballer. I think this is too limited in thinking, although his opinion is always interesting and respected by me, because he has earned his authority to be listened to, but not in this case.
