Sam Allardyce has revealed that West Ham have become the first club to officially register their interest in Bolton defender Tal Ben Haim.
The struggling Hammers have contacted The Reebok Stadium regarding the availability of the defender who is out of contract at the end of the season.
Whilst The Trotters are doing their utmost to convince Ben Haim that his future is best served by staying at the club, a transfer battle for his signature looks set to ensue now Alan Curbishley has made his move.
The London side are in need of reinforcements in order to steer clear of the relegation zone and Allardyce has now confirmed that he has received an enquiry from Upton Park regarding his star defender.
"We've had an enquiry from West Ham," Allardyce told the Bolton News. "But that's all."
Ben Haim has also been linked with Chelsea and Portsmouth after refusing to commit his future to Bolton, but Allardyce is determined to try and keep hold of the former Maccabi Tel Aviv star.
Indeed, the Trotters boss is currently focused on strengthening his squad rather than losing a key element of his defence.
"The last thing we want is somebody going out," Allardyce added.
"If we can get one or more in, that would be fantastic. In the position we are in, we don't want to get too distracted by all the media speculation that revolves around the January transfer window and focus on our big game against Manchester City."
Allardyce has also denied that Ben Haim missed the FA Cup win over Doncaster to prevent him becoming cup tied.
