Chelsea have offered Stamford Bridge's naming rights to Brazilian oil firm Petrobras.
The Premier League leaders have extended the proposal to the South American firm with a view to renaming the west London stadium Petrobras Stamford Bridge, says the Daily Mail.
However, Brazilian magazine Veja reports that the business opportunity will be rejected by the company.
Petrobras is also said to have been approached by Manchester United before the club signed a shirt sponsorship deal with American insurers AON to replace AIG.
