West Ham have made a third bid for Brentford striker Scott Hogan, Sky sources understand.

The Hammers had a second offer of £10m for the 24-year-old turned down on 5 January and the latest bid is believed to be worth up to £12m. The Championship club value Hogan at £15m and talks are on-going.

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. Rochdale have a sell-on clause of 30 per cent as part of the deal that took him to Griffin Park.
