West Ham chairman David Gold has confirmed that Andre Ayew will be out for four months with a quadriceps injury suffered in West Ham’s opening Premier League game with Chelsea.

Gold posted a photo of Ayew on Twitter confirming the injury and length of absence, and wished the forward the best of luck.

Ayew started the 2-1 defeat at Stamford Bridge but pulled up in the first half with a thigh problem and was immediately substituted.

The length of his absence was first reported by Jack Sullivan, son of joint owner David Sullivan, on his personal Twitter account on Wednesday.

It will be a huge blow for West Ham just a week after the 26-year-old’s £20.5million transfer from Swansea that smashed the club’s transfer record.

The Hammers prised the Ghana international from their fellow Premier League club after an exhaustive search to find a new forward.

The Londoners have been in hot pursuit of a striker this summer, but with Ayew now out injured for a large period of time, new signing Jonathan Calleri may be called upon.

The 22-year-old striker signed a season long loan from Uruguayan side Deportivo Maldonado on Tuesday.
