Diafra Sakho is poised to agree a new improved deal with West Ham, even though he is just four months into the five-year contract he agreed when he joined the club.

Sakho, signed from French club Metz for £3.5million in August, has proved to be an outstanding buy, scoring seven goals in his first 10 games for West Ham.

Sakho originally signed a £15,000-a-week deal but the new offer, which will kick in after he makes 25 appearances for the club, is worth an extra £10,000 per week plus bonuses to the Senegal international.

A happy Sakho posted a picture of himself and David Sullivan at the West Ham co-chairman’s house earlier this week, where negotiations took place.

Sullivan was instrumental in the summer move for Sakho when it looked likely that a proposed deal would fall through. Manager Sam Allardyce’s No1 target was Sunderland’s Connor Wickham but when that deal didn’t progress, Sullivan stepped in to seal the deal for Sakho.

Meanwhile, long-serving midfielder Mark Noble is also in line for a new deal, with the club ready to take up a two-year option on his current contract and offering him three more years on improved terms.

Noble remains a doubt for Saturday’s home match against Leicester with an Achilles tendon injury.
