The Hammers have signed Ryan Fredericks and Jack Wilshere on free transfers, while Lukas Fabianski and Issa Diop were followed by West Ham's latest signing Andriy Yarmolenko from Borussia Dortmund this week.
Deals for South American duo Felipe Anderson and Fabien Balbuena are reportedly set for completion over the weekend and will take West Ham's spending past the £90 million mark this summer (The Sun).
Hammers fans are loving life, but many have concerns over Yarmolenko's ability to cut it in the Premier League following a poor season after his big move to Borussia Dortmund.
The Ukrainian was not the same player who had shone so brightly for Dynamo Kyiv - and his national side - when he made his big move to Germany.
"At Dortmund, he had some good matches but perhaps didn’t quite show his very best," Husillos told whufc.com.
"However, I think Manuel Pellegrini is the perfect coach for Andriy and his style of play.
“I believe he is joining us in the perfect moment.
"He is 28, the prime age for football, and we have great expectation about what he can achieve with West Ham United."
