West Ham United vice-chairman Karren Brady has told the club's fans to expect more signings before the beginning of the season.
The Hammers have already completed the signings of Mohamed Diame and Jussi Jaaskelainen this summer, with more signings expected to follow.
"We hope to bring in a few more significant signings to improve our team and increase our chances of remaining in the Premier League and really 'have a go'," she told Sky Sports News.
"We want to compete and really make a contribution to this league. West Ham are a great club who deserve to play in the greatest league in the world.
"Sam [Allardyce] has made a very strategic plan. We have a comprehensive list of players we hope to bring in and we are working to do that."
West Ham secured Premier League football via the Championship playoffs last season.
