West Ham forward Diafra Sakho is believed to want his future resolved quickly amid reported interest from Sunderland.
The Senegalese international joined the Hammers from Metz in the summer of 2014 and has scored 15 goals in 44 Premier League appearances for the east London outfit.
The 26-year-old has been heavily linked with a move to Sunderland over recent weeks, where his former boss Sam Allardyce is the manager, and the Black Cats reportedly made an Â£11million bid for the forward earlier this week.
Sakho is now believed to want his future resolved one way or another before the start of pre-season, as he is keen to begin his preparations for the new campaign at the club where he will be playing his football.
The frontman is aware that West Ham are in the market for a new striker this summer, with the likes of Carlos Bacca and Alexandre Lacazette being linked with a move to the Olympic Stadium, meaning his playing time could be limited if he remains with the Hammers.
