West Ham are set to complete the signing of Kevin Nolan on Thursday and make him their new captain.
The Hammers have revealed they expect to complete two new signings within the next 24 hours, with Bolton left-back Ricardo Gardner also poised to arrive at Upton Park.
"Both prospective arrivals are proven Premier League players and will add greatly to new manager Sam Allardyce's first-team squad ahead of the 2011/12 season," read a club statement.
Newcastle midfielder Nolan is due to undergo a medical after the clubs agreed an undisclosed fee for him.
It is understood the 28-year-old is keen to be reunited with Allardyce, whom he played under at Bolton, and that he will be appointed skipper at Upton Park following Matt Upson's departure.
He will also fill the void in the midfield set to be left by Scott Parker's likely move back to the Premier League this summer, following West Ham's relegation.
Jamaica international Gardner, 32, is available on a free transfer after seeing out his contract at the Reebok Stadium.
Allardyce has already brought in defender Abdoulaye Faye, who played for him under Bolton and Newcastle and was a free agent after leaving Stoke.
