Hull City boss Steve Bruce has told BBC Sport that midfielder Tom Huddlestone does have a release clause in his contract - and believes West Ham are aware of that fact.
Huddlestone, 28, joined Hull from Tottenham in the summer of 2013, having seen his Spurs career stagnate due to competition for places and a spate of injuries during his time at White Hart Lane.
Now though, the central midfielder has rebuilt his career, and whilst Hull got relegated from the Premier League last season, Huddlestone has been one of their better players ever since he arrived at the KC Stadium, with his range of passing continuing to impress.
A big, physical presence too, Huddlestone deserves to be back in the Premier League - and The Mirror reported on Saturday that West Ham are closing in on a deal to bring the midfielder back to London.
The Hammers need a midfielder having seen Alex Song return to Barcelona after his loan deal expired, whilst a move for Joey Barton was cancelled last week.
Instead, a move for Huddlestone now looks likely, and Hull boss Bruce told BBC Sport that Slaven Bilic's men are no doubt aware of Huddlestone's release clause - and knows that there is little he can do to keep Huddlestone at the KC Stadium if West Ham do come calling.
"I am sure West Ham, like anybody, knows he has a buy-out in his contract and if they get to that figure I am powerless," said Bruce. "The agents will be touting him around everywhere, which I know they are. But there's nothing I can do."
Huddlestone can bring many of the qualities that Song offered West Ham last season, but he can't get around the pitch quite as well as the Barcelona outcast.
That's due to Huddlestone's giant frame, so he may be better deployed in front of the back four where he can dictate from deep and spray his famous long passes around the pitch - if he does indeed sign for West Ham, as many now expect him to after Bruce's comments.
