“I want to thank everyone for welcoming me including the fans and everyone at the club. I wanted to start a new experience and I feel this is the right choice for me,” Zaza told the club’s official website.
“I have been fortunate enough to have already played at the new stadium with a different shirt. It is a beautiful stadium and I felt the warmth of the fans and this was a big reason why I wanted to join the Club.
“I want to become a better player and I know I can do that at West Ham. Unfortunately we could not qualify for the Europa League, but I am hoping I can help the club do that next season.”
