On this day in 2017, Real Madrid won the Champions League for the 12th time - yes, 12.
That particular night, Zizou's boys dismantled Juventus in Cardiff. Goals from Cristiano Ronaldo - of course - along with Casemiro and Marco Asensio sealed victory for Real. Shame really, since Mario Mandzukic's finish deserved better.
