Andre Ayew had his West Ham debut cut short after sustaining a thigh injury in his team’s 2-1 Premier League defeat against Chelsea on Monday night.

The forward sustained the injury after chasing Eden Hazard back towards his own goal and pulled up after failing to prevent the Belgium international’s shot on goal.

The Ghanaian star left the Stamford Bridge pitch just 34 minutes into the match clutching his right-thigh and West Ham fans will now await further news of the injury.

Given that it appeared to be a muscle injury, Ayew is facing a spell of the sidelines in what is likely to be a significant blow for his new club.

The match was goal-less when Ayew left the pitch as all three goals came in the second half of the match.

Eden Hazard put Chelsea ahead from the penalty spot before James Collins equalised with a thunderous shot and, with the derby seemingly set to end in a draw, Diego Costa scored a late winner with a drive from the edge of the box.

The 26-year-old forward joined the east London outfit earlier this month following his club-record £20.5million move from Swansea.

Ayew was signed by Slaven Bilic as the Croatian boss looked to bolster his attacking options at the Olympic Stadium this season.

The Swansea hitman scored 12 goals last season in all competitions and caught the attention of Bilic during his extensive search for a top class striker.

West Ham had been very public in their pursuit of a top drawer goal-scorer this summer and reportedly failed with bids for the likes of AC Milan’s Carlos Bacca, Lyon’s Alexandre Lacazette and Michy Batshuayi, before settling on Ayew.

Bilic will be frustrated at the early injury and will be hoping that his side’s most expensive ever signing can make a swift recovery and feature extensively in West Ham’s domestic campaign.

In other West Ham transfer news, Paul Merson has picked both Dimitri Payet and Cheikhou Kouyate in his combined Chelsea and West Ham six-a-side team.
