The 18-year-old winger has been the subject of intense transfer speculation in recent weeks, with suggestions that he could be on his way to the Premier League.
Bruma has already drawn comparisons with Portuguese compatriot Cristiano Ronaldo, given his attacking style of play and eye for goal, which has only added to his burgeoning reputation across Europe.
Jose Mourinho has been credited with an interest in bringing Bruma to Stamford Bridge this summer, with some reports suggesting that Chelsea had already lodged a bid for his services.
Manchester City have also been mooted as admirers of the Sporting Lisbon star, with Manuel Pellegrini ready to lure the talented teenager to the Etihad Stadium ahead of the 2013/14 campaign.
However, Bruma's lawyer Bebiano Gomes has told Portuguese newspaper Record that neither Chelsea nor Manchester City - or any other club for that matter - have been in contact regarding a transfer.
With just over 12 months remaining on his existing contract at Estadio Jose Alvalade, the Primeira Liga club plan to open talks with Bruma over a new deal in the coming weeks.
