Yeah, and the champions league indeed is the best place to showcase these valuable experiences. Looking at real madrid from last season, they won just because they have a bunch of serial winners in their team. Who have done it over and over again.
They know what it takes to win this thing. Compared to some teams who have only reached the final a couple times around. madrid don't have the most flair players out there. but experience, that's why the KCM trio was a bermuda triangle.
