I've never doubted Real Madrid in the Champions League and it's true that they have a winning mentality that other clubs don't have, the players carry a bit more ambition in UCL matches even when last season they were a goal down to Bayern Munich but Real Madrid could turn it around to win.
Talking about UCL, as I recall, when the trio of Ronaldo, Benzema and Bale were still playing for Real Madrid, they were behind on aggregate in UCL several times in the last few seasons when it was still using the old format, but Real Madrid were always able to turn things around and advance to the next round, there were many crucial moments shown there. This proves that Real Madrid's mentality is beyond doubt, another thing is that if Real Madrid reaches the final, they never lose. "The UCL trophy as if to be made only for Los Blancos", although the words I wrote are exaggerated, but I feel that, is there anyone here who feels the same way?
