A number of Premier League and European clubs have been credited with an interest in the talented 20-year-old, who was part of the Brazil squad that won the Confederations Cup.
Speculation linking him with a move to Arsenal has raged in recent weeks, though Portugese champions Porto are also in the running.

"Congratulations, Bernard. Double-winner! Confederations Cup, Libertadores... the perfect farewell," Adriano Spadoto posted on Twitter.
Bernard himself was less forthcoming about his chances of a move away from Belo Horizonte, but did suggest that he has achieved everything he set out to with the club.
"I do not know what will happen to me from tomorrow," he said following the victory. "If I stay or not, I have made it clear that I wanted to leave here with a big title, so I have fulfilled my goal, which I promised to fulfil.
"It is up to God to decide if I stay or not, it's up to God and also the presidency, to Alexandre Kalil, to the board."
Atletico Mineiro will now compete in the Club World Cup in December, and it remains to be seen whether Bernard would want to remain with his current side until the January transfer window in order to compete.
Lucas Moura, who agreed a transfer to Paris Saint-Germain last summer, opted to stay with Sao Paulo until December in order to compete in the final of the Copa Sudamericana.
Liverpool, Tottenham and Porto have all been closely linked with the wideman, but Arsenal appear to have stolen a march on their rivals, according to the latest rumours in South America and Europe.
