If anything the underrated hero of the finals (and real's season) is their defense, as they are permanently understaffed back there and still hold out against an exceptional juventus attack, enabling the real attack to put real pressure on juventus and winning them the match indirectly. Imo the key difference between real and barcelona is that real can get away with a couple of defenders against world class compe ion. That's why real can put so much pressure on offense, because they defend properly with less people.
Tldr ramos and varane they are reaaally underrated.
