"The club's position remains the same as it was last week or as it was in January: there is no question of [Icelandic bank] Straumur forcing us to sell anyone - in fact we are actively looking for new players," he said.
"The papers are unsurprisingly full of speculation at this time of year, but the situation is clear - the only way a player would be allowed to leave is if Gianfranco thinks it is in the best interests of the squad as a whole and it is right for the club."
West Ham's non-executive chairman Andrew Bernhardt added: "We fully support Scott and Gianfranco and endorse their continued efforts in strengthening the squad as quickly as possible, with a new striker their top priority."
CB Holding, which is owned largely by Icelandic investment bank Straumur-Burdaras assumed ownership of the Hammers from previous chairman Bjorgolfur Gudmundsson in June.
