Liverpool goalkeeper Alisson is spending his Premier League break training at home with Fluminense.
Alisson has remained keen to stay sharp and linked up with his brother, Muriel, who is goalkeeper for the top flight club.
O Globo says the goalkeeper has requested not to be photographed at any training sessions at the club as he aims to avoid a big deal being made of his presence.
The Serie A club have also declined to comment on Alisson's presence, saying they are unable to speak about a player who does not belong to them.
Alisson attended the Maracana on Wednesday night, watching Muriel play in goal as they drew 1-1 with Chilean club Union La Calera in the Copa Sudamerica, South America's version of the Europa League.
