The Hammers won promotion to the Premier League in May's play-off final and have already signed goalkeeper Jussi Jaaskelainen, with the co-chairman hinting at further arrivals
West Ham co-chairman David Gold has revealed that the club intend to sign up to four players over the summer ahead of the start of the season.
The Hammers won promotion to the Premier League under manager Sam Allardyce after defeating Blackpool 2-1 in the Championship play-off final at Wembley.
"We're connected with about 20 players," Gold told Sky Sports News.
"What we hope to do is to maybe bring in two, three or maybe four players by the close of the window as we start off in the new season."
Players linked with a switch to East London include former Real Madrid midfielder Guti, who is available on a free transfer having been released by Turkish club Besiktas, and Norwich striker Grant Holt, whose transfer request was rejected by the Canaries last month.
Goalkeeper Jussi Jaaskelainen is set to join the club in July, departing from relegated Bolton.
The board member also explained how the club tried to persuade England’s reserve goalkeeper Robert Green to stay at Upton Park, before he left having failed to agree terms on a new deal.
"We did our very best and we're very sad that we have lost Robert," Gold admitted. "We wish him well, and wherever he goes I'm sure he will be a great servant to that club."
