Sebastian Vettel was put on the spot following his Grand Prix win in India when he was forced to deny rumours of a move to Ferrari.
The Red Bull driver earned his fourth consecutive victory to lift him 13 points clear of his nearest rival Fernando Alonso in the race for the Formula One world title.
"No, there's nothing, nothing to tell you, nothing I've signed, nothing has changed," said Vettel said after the win.
"I don't know where it came from. I don't read much, so it's quite a surprise when you get to the circuit and get all these questions.
"Actually, there's one thing I would like to say about this - you don't know every single one in the team, and it's hard to speak to every single one.
"So if there's some rubbish in the press, obviously there might be some concerns back in the factory.
"But I'm 100 per cent behind them as I feel they're 100 per cent behind me.
"Therefore I want to get this straight - there's nothing to report and I'm very happy at Red Bull Racing."
