Yes, I also often comment when Real Mandiri experiences a little bad performance at the beginning of the competition and I always say that Real Madrid is a team that always creates surprises. And maybe at the beginning Real Madrid often does not appear impressive but in the middle of the competition Real Mandiri's performance changes drastically and also always wins the match, and I am not surprised if Real Madrid often makes a comeback and that often happens in the UCL and indeed Real Madrid has long been dubbed the comeback king so I am used to it because the results will always be perfect for Real Madrid when playing against any team, even when in the first leg getting a big defeat Real Madrid can turn things around.
Real Madrid strongly believe in their capability and by winning many Champions League title last decade, their players have very strong confidence and mentality so that they are very hardly beaten squad with this player generation. After a successful generation with Ronaldo, Bale, Benzema, Modric, Kroos, Casemiro, Ramos, Real Madrid succeeded with their transition and they even won Champions League in those transitional seasons.
The management of Florentino Perez helped Real Madrid to have very good development, transfer and salary strategies so that Real Madrid are able to have good finance, success in transfer market, and many titles on field. In many years, they don't have big problems with transition like Manchester City in this season.
By the way Sergio Aguero made an extreme bet whether he did it other than losing money.
He did not lose anything, not cut his "balls" by himself after this defeat.
