West Ham have reportedly stepped up their interest in Brentford's Scott Hogan, with the Championship outfit standing firm over their star striker.

According to the ​Mail, the Hammers are in talks over a £10m switch, but Brentford are understood to want closer to £15m for the 24-year-old.

Hogan has attracted interest ahead of the January transfer window after banging in 14 goals in 25 appearances in England second tier - with West Ham identifying the hitman as a solution to their goalscoring problems.

The London Stadium outfit haven't been able to rely on the contributions of their forwards after Andy Carroll and Diafra Sakho's injury lay-offs and the dismal form shown by Simone Zaza.

West Ham might have to move quickly given that speculation has linked Hogan to Watford, Reading, Norwich, Aston Villa and even German side Red Bull Leipzig.

With 14 goals to his name already, the former Rochdale man has found himself a wanted man by the Hammers - who failed with a £6m bid to bring veteran Jermain Defoe back to the club.

The move for the 34-year-old was largely mocked on social media, given the age of the former Tottenham hitman and his huge importance to Sunderland in their relegation battle.

Defoe has bagged 11 Premier League goals already this term and is crucial to the Black Cats' bid to stave off the threat of the drop.

It is understood that West Ham officials could go back in with an improved offer for Defoe, but are unlikely to prize him away from the Stadium of Light given what is at stake for David Moyes' men.​
