Real Madrid coach Carlo Ancelotti backed winger Vinicius Junior to escape Ronald Araujo's shackles when Los Blancos face Barcelona on Sunday in the Clasico in La Liga.
The Brazilian winger, key for Madrid this season, has been shut down by Barca defender Araujo in recent clashes with the Catalans, with coach Xavi Hernandez deploying the centre-back on the right to directly confront him.
Vinicius has scored twice in 12 games against Barcelona, both times before Barcelona started using Araujo at right-back.
No player has scored from open play against leaders Barca at Camp Nou in La Liga this season, giving champions Madrid a formidable task as they try to eat into the nine-point deficit between the sides.
"He's had more difficulties than in other games, but Vini is always Vini, his mobility can help him get best (from himself) in tomorrow's game," Ancelotti told a news conference Saturday.
"I'm thinking of putting him on the right, let's see. He can play on the right, Vinicius."
Ancelotti later said he was joking about using Vinicius on the right flank, but reiterated that the forward could be given more liberty to drift from the left.
"Obviously that wasn't serious, but mobility could be important, not having a fixed reference point. Speaking generally, against a forward that's another problem for a defence.
"Vini will play on the left, with more mobility."
Xavi also looked forward to the battle between Araujo and Vinicius.
"Araujo is very physically strong, he's quick, fast, and understands the movements of his opponents," Xavi told reporters Saturday.
"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."
Xavi said he was looking forward to coaching in the Clasico at Camp Nou for the first time, with his prior clashes with Madrid all taking place away from home.
