The Broncos announced their intention to leave Twickenham Stoop earlier this year, and are currently without a home venue next season.
Their fixtures for 2014 were revealed today, despite the fact the club has laid off most of its off-field staff, and has just five players under contract.
Kleanthous told the BBC: “They talk a lot, that is for sure. I don’t know whether something will or won’t happen.
“At the moment I can assure you there is no deal. But who knows?”
“The RFL are a pretty forward-thinking organisation. I am quite impressed by them, although they have got some in-fighting going on at the moment. But that is happening in all sports.”
The Broncos have played at Twickenham Stoop since 2006, having previously played at Griffin Park.
They are due to open the Super League season with a trip to Widnes on Friday February 16.
