In previous El Clasico era, talks of Cristiano Ronaldo and Lionel Messi was a battle to watch out for.

However, Ronald Araujo’s battles with Vinicius Junior have become one of the hallmarks of recent El Clasico clashes.

Vinicius has scored 19 goals in all competitions this season but has failed to score in his past three direct match-ups against Araujo.

Against Real Madrid, Xavi switches Araujo from centre-back to right-back to face the Brazil international.

Vinicius has scored twice in 12 games against Barcelona, both times before Barcelona started using Araujo at right-back.

The Barcelona defender has vowed to be at his best against Vinicius.

“For me, right now, he is the No. 1 player in that position, in one-on-one situations,” Araujo said of their duel.

“He’s a really good player, he can unbalance teams.

“It’s difficult to play against him, of course, but I have been working hard so that I can be at my best, too, and I’m glad that things have been going well for us in that regard.”
