The forward joined in a £20 million move from Swansea City earlier this week.
The Hammers had been on the hunt for a new striker all summer, seeing bids for Michy Batshuayi and Alexandre Lacazette in particular fail.
They decided to look closer to home instead, bring Ayew to the Olympic Stadium in a £20 million move from Swansea City earlier this week.

At that price the move has been questioned by some, despite the forward impressing with the Swans in the Premier League last season.
Noble is enthused about the move though, saying he was over the moon when he initially heard of West Ham’s interest.
“I think he’s top quality,” he told Premierleague.com.
“I played against him twice last year and he was on a different gear. As soon as I saw that were in to sign him I was over the moon.”

It will now be interesting to see if Ayew can be the regular goalscorer that West Ham lacked last season.
He managed more goals than all of their forwards last season so he is certainly an upgrade in that regard, although it is debatable whether he is the out and out 20-goal-a-season striker that they need.
In a better side with the like of Dimitri Payet supplying assists, there is every chance he could enjoy an even stronger season than his first.
