Daniel Ricciardo has said he still hasn't signed a deal with Red Bull Racing for the 2014 F1 season - and that as far as he is concerned the seat alongside Sebastian Vettel is still 'up for grabs'.

Red Bull had been expected to make an announcement this weekend in Belgium, with Ricciardo tipped to get the nod after talks with Kimi Raikkonen - the other main candidate in the frame - broke down.

However, Red Bull advisor Helmut Marko later backtracked and said there would be no confirmation of who will replace Mark Webber at Spa-Francorchamps.

Quizzed on the matter in the countdown to the eleventh round in the 2013 F1 World Championship, Ricciardo insisted he is still in the dark about whether or not he will get the nod to progress to Red Bull's 'A' team.

"There's nothing yet and until the call comes from someone over there [Red Bull] about the decision then as far as I know I am just here for this year and don't know anything about next year," the Toro Rosso pilot told Sky Sports F1.

"I've learnt that until something is signed, sealed and delivered then nothing is ever concrete, particularly in this environment," added the Aussie. "Whether that is true or not, who knows, but there are a lot of drivers on the grid with great credentials, and so until something is done I am not going to be celebrating or getting my hopes up."

"I'm not going to assume anything, as far as I am concerned there is still a seat up for grabs," he concluded.
