There is no doubt that Real Madrid has been trusted by many people to become champions again this season. Especially when they managed to beat Manchester City. The match was like determining who would be the champion, I mean whoever won the match was believed to be the champion, and Real Madrid managed to win the match well.
Yes, because compared to Dortmund, Real Madrid has much more experience in UCL finals, in fact this seems like Dortmund's first final in the UCL, right? Apart from that, so far, Real Madrid's performance is also considered much better and stronger than Dortmund's, not only in the UCL but also in their respective domestic leagues. We no longer doubt how Real Madrid can do it, especially with their coach who is truly excellent, there is no doubt that Ancelotti is very smart in making decisions that are sometimes quite different and surprising, but they work.
It just doesn't mean we underestimate Dortmund. Because they also have high motivation to win the match and take the UCL trophy. They may seem underestimated for some particular reasons when looking at their poor performance in the Bundesliga, but in the UCL, they look quite different from their abilities so far.
