West Ham have confirmed the signing of midfielder Joey O'Brien on a free transfer after he was released by Bolton earlier this summer.
The Republic of Ireland international is reunited with new Hammers boss Sam Allardyce after previously working under the manager at the Reebok Stadium.
O'Brien has spent pre-season with the East London side and has impressed enough to earn a deal at Upton Park.
The 25-year-old, who was on loan at Sheffield Wednesday last term, becomes Allardyce's fourth new signing, joining Kevin Nolan, Abdoulaye Faye and Matt Taylor at Upton Park.
"Obviously I'm delighted to finally sign because I've been here since the start of pre-season," he told the club's official website.
"It's been a few weeks now and it's gone well. The manager wanted me to sign and as soon as I heard that, there was no real hesitation."
Allardyce is also weighing up the signing of a fifth former Bolton player, full-back Jlloyd Samuel, who is playing in Saturday afternoon's friendly against Real Zaragoza.
