Osasuna winger Kike Barja says Vinicius Jr was constantly taunting his opponents throughout Real Madrid's Copa del Rey final win.
The Real star was again superb for the Copa triumph on Saturday.
Barja said: "It is painful to have a title there and for it to slip away, but we knew about the difficulty and the quality that Real Madrid has. The first goal was a very hard stick, because you may have doubts, but the team recovered very well and when the tie came there was a moment of explosion that was special for everyone. We stood up to one of the best teams in the world being a modest club."
Barja says Vinicius drove Jon Moncayola "crazy" during the game: "He told me that the first half is the worst that has ever happened, in the end he is not a specialist in that position and he has face a player with world-class talent.
"Moncayola tells me that he was constantly telling him things to get him out of the game, so you have to see everything.
It is clear that he receives a lot of fouls and that you have to protect the players, but he also has to understand that he receives a lot of fouls because the defenders have to stop him in some way. He generates controversy and he has to see what he can improve and correct because he has problems with all the teams. Vinicius gets out of the game very easily and makes very ugly gestures to the stands and celebrating in the face of the rivals."
