West Ham United manager Sam Allardyce is set to bring in another of his former charges, in Leeds United defender Andy O'Brien, according to the Sun.
The 32-year-old could become the fifth former Bolton player to sign for the Upton Park club following the signing of Matt Taylor, Joey O'Brien, Kevin Nolan and Abdoulaye Faye during the summer.
O'Brien has been told he will never play for Leeds again after refusing to play against Burnley on Saturday.
“Andy O’Brien came to me on Friday and said that he no longer wanted to play for this football club," Grayson said.
"It came as a shock on Friday but he won’t play for this football club again as long as I am here.
"It came as a shock, especially after I have backed him publicly and privately over the last few weeks.
West Ham could now be tempted to bring on O'Brien, not least because of Allardyce's relationship with the player, but due to the manager's insistence that the club bring in reinforcements in the area.
Winston Reid is ruled out with a shoulder problem, and West Ham boss Allardyce is adamant he needs cover until the New Zealander recovers.
"My main priority is to find a central defender to loan for the next two or three months," Allardyce said.
Without O'Brien in their ranks, Leeds rallied late to beat Burnley but could be forced to delve into the transfer window in order to find back up for the Republic of Ireland centre-back.
United are looking to bring in Northern Ireland goalkeeper Maik Taylor as back up for Alex McCarthy, whose performance helped Grayson's men on tier way to a second successive away win.
