The club announced that the south-London club had made a bid and Wednesday confirmed it was around the £1.3million mark.
Rumours surfaced that the Algerian had a clause in his contract which states he can talk to interested parties if a bid of over £1million is received but that seems to be wide of the mark.
Chief executive Kaven Walker has said that the star defender is not for sale although it is expected that Athletic boss Alan Pardew may table an improved bid before the end of January.
