West Ham United boss Sam Allardyce is frustrated by his team's inconsistency.

They have also taken just one point from 21 in their last seven away matches. But, at Upton Park, they have lost just three all season.

Allardyce, 58, said: "We are a Jekyll and Hyde side. It niggles me we can't replicate our home form on our travels.

"Away from home, we have the worst goalscoring ratio - even though we have been putting the opposition under real pressure."
