Real's record 12th triumph in this competition - and third in four seasons - was predictably orchestrated by Ronaldo, who has now scored in three different Champions League finals.

Ronaldo stopped a bright Juve opening in its tracks as he swept in Dani Carvajal's pass after 20 minutes, before Mario Mandzukic levelled with one of the great Champions League final goals, firing a sublime overhead kick beyond Real goalkeeper Keylor Navas.

Real were unstoppable after the break, restoring their lead through Casemiro's deflected shot before Ronaldo scored at the near post from a cross by the outstanding Luka Modric.

Juventus' misery increased when substitute Juan Cuadrado was sent off for a second caution after a clash with Sergio Ramos, before substitute Marco Asensio emphasised Real's superiority with a precise finish in the last minute.

Real coach Zinedine Zidane has now won back-to-back Champions Leagues - as well as this season's La Liga title - since he took charge in January 2016.
