West Ham boss Sam Allardyce has refused to reveal details about Momo Diame's release clause amid suggestions that several Premier League clubs want the in-form midfielder.
Diame, who arrived at Upton Park on a free transfer from Wigan during the summer, has been one of the signings of the season so far.
His introduction as a half-time substitute during West Ham's recent 3-1 win against Chelsea fuelled the Hammers' second-half revival and he was rewarded for his efforts with a well-deserved goal.
Recent reports suggested the 25-year-old has an escape clause in his contract which would allow him to leave east London for a knockdown fee.
But Allardyce has not confirmed whether or not this is the case, before expressing his belief that scouts are monitoring the Senegal star.
He said: "I can't discuss personal contracts, obviously. But when people start playing consistently well scouts are always watching and agents get very busy."
