It is being reported that West Ham United striker Diafra Sakho has refused to travel with the rest of the squad for their pre-season tour of Austria.
Sky Sports News is reporting the news that the Senegalese striker has not travelled with the squad as his future remains up in the air at the London club.
The news will still come as a blow to West Ham boss Slaven Bilic.
The Hammers are well known to be on the hunt for a new striker, as they were short in this area last season, but with Enner Valencia looking likely to depart the exit of Sakho will leave West Ham significantly short.

Sunderland have been heavily linked with a move for Sakho in recent weeks, but the deal appears to be being held up by the FA’s pursuit of Sam Allardyce for the England job.
Sky Sports recently reported that Sakho wanted clarification over his future amid the links to Sunderland – with concern he may be about to drop further down the pecking order as West Ham hunt for a top class striking option.
