Real Madrid management have slated Vinicius Junior to join their preseason tour this year.
Vinicius, who signed for Real a year ago, has been outstanding for Flamengo this season and has expressed hope of playing out the year in Brazil.
However, Marca says Real want him to join them for their tour of the US in July, where he will be assessed by coaching staff.
A loan move to a LaLiga rival is expected for the 17 year-old, though if he impresses, Vinicius Junior could be registered with Real for the new season.
Real made the attacker the richest 16 year-old transfer in January 2017 for €45m.
