Osasuna midfielder Jaume Grau has spoken of playing with Vinicius Junior last season.
The on-loan Lugo midfielder said, "He came on the last day before the game to train with us and then play. You saw he had something different to everyone when he took the ball.
"I am very happy to have been able to play alongside him."
Grau made the bench last season for a Copa del Rey tie and added: "The experience was incredible. The build up, when you go on the bus to the field, in the locker room when they give the lineup, is a unique experience that I will always remember."
