American investment firm Cain Hoy said Friday they were contemplating a bid to buy Tottenham Hotspur. The English Premier League club had rejected suggestions on Thursday that their Bahamas-based owner Joe Lewis would sell the north London side if offered in the region of £1 billion ($1.6 billion, 1.2 billion euros). But Cain Hoy said Friday they were in the initial stages of preparing a bid, which they emphasised had taken place without the consent of the Tottenham hierarchy. They now have until October 10 under English take-over rules to make a formal offer or announce they are no longer interested in purchasing Spurs.
