Bernie Ecclestone insists the future of the Italian Grand Prix remains in doubt and says he has no idea whether a new agreement will be reached.
The Italian Grand Prix has been a permanent fixture on the Formula One calendar since its inception in 1950, with Monza playing host to every race bar one.
However, the iconic track's most recent deal expires at the end of next season and Formula One chief Ecclestone is already on the record as saying there is a "good chance" it will be lost.
Asked if a new deal will be signed, Ecclestone, 84, said: "No idea, I haven't got a clue. We're happy to be at Monza obviously but we're not doing cut-price things."
The Formula One paddock heads to Monza for the Italian Grand Prix in a fortnight's time, and Ecclestone added: "We'll see when we get there. They've got a contract, all they have to do is find a pen. It's easy.

"We had a deal with them two years ago, so if they just continue with it it's okay."
Ecclestone also revealed that the Russian Grand Prix, which will take place in May for the first time next season to coincide with a national holiday, could host its first night race within two years.
"We have talked about it, maybe 2017," Ecclestone, flanked by Russian Grand Prix chiefs Alexander Saurin and Sergey Vorobyev here in Spa, said.
Circuit organisers are in early discussions over extending the seven-year contract they signed in 2014. Ecclestone added: "You can book your tickets for the next 10 years."
