Compare success and experience from the past, Real Madrid have more than Leverkusen and they can use it to avoid a shocked loss like Leverkusen. With many final matches in Champions League, Real Madrid know that if they give an opponent time, space and chance, the opponent can punish them with a conceded goal that is always big disadvantage in any final match. Chance to come back in a final match is smaller than in other matches because opponent players will use all energy they have for fight.
That's why I don't want to equate the quality of Real Madrid with other teams like Leverkusen who lost in the Europa League final and Manchester City who lost in the FA final. Because if we equate one team with another team, why can't we equate one platform with another platform or one car with another car with a different brand?
The reason I don't equate Real Madrid with any team is the fact that in the final match itself, Real Madrid only lost three times out of the 18 times they entered the Champions League final, so this season Real Madrid has succeeded in winning the Champions League title for the 15th time. This is proof that every team should not be the same because every team has a different level of strength and luck in every match, whatever it is.
