One of the biggest duels people are looking forward to seeing in the El Clasico clash on Sunday, is between Vinicius Jr and Ronald Araujo.
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 usually switches Araujo from centre-back to right-back to face the Brazil international.
Speaking ahead of the game, Xavi said: “Araujo is very physically strong, he’s quick, fast, and understands the movements of his opponents.
“He’s responsible, and a leader. He’s a world class defender, one of the best in the world. Having Ronald in the team, is a guarantee, an advantage.
“Usually when he takes on Vinicius, he comes out as the winner of the battle, but Vinicius can make a big difference.
“It’s not just Ronald, it’s (everyone) looking out, and collectively, we’ve been very good against Madrid.”
