The forward joined the Hammers from Swansea City this week.

The Hammers have been seeking a striker all summer, with them linked to a number of forwards across Europe.
They had been met with frustration though as bids for the likes of Michy Batshuayi and Alexandre Lacazette failed.

Instead they turned their attention to the Premier League and opted for Swansea City’s Ayew, paying £20 million for his services.
The price surprised some despite him impressing in the Premier League last season, and Nicholas says he feels the deal was a bit much.
“I thought it was a bit pricey but then again everything is pricey at the minute,” he told Sky Sports.
“He’s a decent player. He seems the type who, playing with better players, could get better again. There’s a lot I do like about him [but] it’s a lot of money.”

It now remains to be seen whether Ayew proves to be value for money across this season.
There is no denying that he has the quality to be a success, but it is debatable whether he is the out-and-out striker that their side needs.
Should he prove that he is by scoring the goals they need, however, there will not be many questioning the price they have paid for him by the end of the season.
