David Sullivan has challenged West Ham's new signings to win silverware and take the club to the next level - with the joint-chairman saying belief and luck is key to a successful season.
The Hammers have had a busy seven days in the transfer window, signing Joe Hart, Marko Arnautovic and Javier Hernandez from Manchester City, Stoke and Bayer Leverkusen respectively.
