West Ham have had a second bid for Brentford striker Scott Hogan rejected, Sky sources understand.
The Hammers had a £10m offer for the 24-year-old turned down on Thursday.
A "buttock injury" kept Hogan out of the Brentford squad for their FA Cup third round tie against Eastleigh but the Bees expect him to return to training on Monday or Tuesday.
Talks with West Ham - who themselves exited the FA Cup with a 5-0 home defeat to Manchester City on Friday night - remain ongoing.
Hogan has 18 months left on his current contract at Brentford and is willing to leave in January in order to secure Premier League football.
The 24-year-old is valued at around £15m by the Sky Bet Championship club and Sky sources revealed on Monday that Bundesliga side RB Leipzig were also interested in signing him.
Hogan, who joined Brentford from Rochdale in a £750,000 deal in 2014, has scored 14 goals in 26 appearances this season.
