The Ukrainian has taken to social networking site Twitter to express his reaction after making the move. He wrote:

Yarmolenko then underwent a medical at West Ham’s training camp in Switzerland earlier this week before completing the move.
He becomes Manuel Pellegrini’s fifth signing since taking over as West Ham manager.
The club have recruited Jack Wilshere (free), Ryan Fredericks (free), Lukasz Fabianski (£7m, Swansea) and Issa Diop (£22m, Toulouse) already.
Yarmolenko is a versatile forward who is a proven goalscorer. He would add great quality and depth to the Hammers squad.
West Ham fans took to Twitter to respond to his message and they have given him a warm welcome.
Welcome to the academy! Good luck…and enjoy it! 👍⚒⚒⚒
