Under the watchful eye of former Real Madrid legend Cristiano Ronaldo, Sunday's El Clasico perhaps saw the next star born for Los Blancos, Eurasia Diary reports citing CNN.

Vinicius Jr.'s opening goal against Barcelona meant the 19-year-old became the youngest scorer in the fixture in the 21st century, beating Lionel Messi's previous record by 26 days.

Mariano Diaz added the second goal in stoppage time to seal a 2-0 win as Real regained the lead at the top of La Liga with 12 games of the season remaining.

It was the first time in 1,954 days, a wait of more than five years, the Real had beaten Barcelona at the Bernabeu in La Liga.

Barcelona really should have gone iin at the half-time break ahead after a lackluster opening 45 minutes from Real, with Thibault Courtois producing two smart saves to deny Arthur and Messi.

There was a drastic improvement from the host after the interval and this time it was the turn of Barcelona goalkeeper Marc-Andre ter Stegen to steal the show, twice denying Isco with two brilliant stops.

But there was only so long the German stopper could single-handedly keep Real at bay and even then it took a slice of good fortune for Vinicius to break the deadlock, his shot deflecting off Gerard Pique and wrong-footing the keeper.
