Chelsea are in advanced talks with Diego Costa, but are yet to agree a new contract, according to Sky sources.
Media reports on Tuesday suggested that a deal had been struck to keep the Spain international at Stamford Bridge, but Sky sources understand that they are premature.
Costa – who has two full seasons left on his current contract – has scored 15 Premier League goals this season to help propel Chelsea into an eight-point lead at the top of the table.
But he was heavily linked with a move away from west London in the January transfer window, with Chinese club Tianjin Quanjian appearing to be a potential destination.
The 28-year-old was pictured training on his own after falling out with boss Antonio Conte.
But the pair patched up their differences and he was restored to the first team. Conte said last month that he expected Costa to stay with Chelsea for a long time.
Costa has been a huge hit at Chelsea since his £32m move from Atletico Madrid in the summer of 2014.
