The Hammers have already added eight players this summer.
The Hammers have been busy so far in this summer transfer window, with eight new signings arriving at the club so far.
This week in particular has been a busy one, as Andre Ayew, Arthur Masuaku and Jonathan Calleri have all completed moves to the Olympic Stadium.

They will be needed too, with the Hammers hoping to secure their place in the Europa League group stages via a win over Astra Giurgiu in their knockout tie.
However, it appears they are not done with their business yet as he is targeting another signing before the end of the window.
“I spoke to the chairman and said that, with or without European football but especially if qualify,” he told the Daily Mail.
“We need one more player to have to good balance. Maybe we are going to try and get one more but I’m happy with the squad now.”

It now remains to be seen what area of the team that Bilic will look to improve before the end of the window.
He has added to his squad in several areas this summer, with him now possessing more options across the field than he did last year.
It is hard to see where else he would want to improve as a result, and it will make for interesting viewing to discover who that final signing is.
