Chelsea’s Andrey Santos was in attendance at Vasco da Gama vs Boavista on Monday.
The 18-year-old is set to return on loan to Vasco, after they and Chelsea agreed terms on a loan move until the end of June.
Chelsea signed Santos in January but they were unable to get a work permit for him to play in England.
The midfielder, who will likely represent Brazil at the Under-20 World Cup which starts in May, will return to Chelsea in July - with the hope that a work permit will then be granted.
