West Ham have had 'exploratory discussions' about a possible takeover of the club but insist talks are at an early stage.
Kia Joorabchian's company, Media Sport Investment, have been linked with a takeover of the Hammers.
Joorabchian made an investment in Corinthians in December 2004, with Argentinian duo Carlos Tevez and Javier Mascherano leaving the Sao Paulo side and arriving at Upton Park from the Brazilian club yesterday.
A statement to the Stock Exchange from West Ham read: 'The board confirms that it has had exploratory discussions in relation to a possible bid but these discussions are at a very early stage and there can be no certainty that an offer for West Ham will be forthcoming.
However, the east London club insist there is 'no contractual link' between any potential takeover and yesterday's sensational signings of Argentina internationals Javier Mascherano and Carlos Tevez.
West Ham would not confirm who they have been in talks with.
MSI, who owned both players after buying them for their previous club Corinthians, had been investigating a possible takeover bid last summer.
