Brentford are standing firm on their £15million valuation of Scott Hogan after rejecting an improved bid of £12.5m from West Ham.

West Ham have already had offers of £10m and £11.5m turned down and Brentford are adamant Hogan will not leave unless their asking price is met.

Brentford intend to dig their heels in over the 24-year-old forward and are willing to let the transfer saga rumble on until West Ham to meet their valuation.

West Ham know Brentford want £15m but their bids so far have been below that figure.

Brentford are refusing to budge as they seek £2.5m more for a player who has scored 14 goals in 25 matches this season.

Hogan, who is the joint-third highest scorer in the Championship, did not take part in full training yesterday as he recovers from a glute injury.

Brentford are willing to sell Hogan because he has 18 months left on his contract and feel their £15m is a fair reflection of his value in the current market.

Rochdale, Hogan’s former club, are entitled to a percentage of his transfer fee.

Hogan wants a move to the Premier League and Brentford feel he may have played his last game for the club.

But the Bees are not willing to let Hogan complete a cut-price move away from Griffin Park and intend to take a resolute stance with West Ham.
