Daniel Ricciardo has not completely ruled himself out of the 2017 'silly season'.

Last year, the Australian put forward his name as a contender to switch to Ferrari, but Red Bull officials are once again insisting that Ricciardo is firmly under contract.

However, when asked by Italy's Corriere della Sera about his contractual situation at present, Ricciardo answered: "It's open.

"It all depends on Red Bull. If they stay in F1, I think they will propose a multi-year extension."

As for those constant Ferrari rumours, meanwhile, the 26-year-old said: "It will depend on the results and the proposals that I receive and if another team says to me 'We want to try to win the championship with you'."

Ricciardo is currently fourth in the standings ahead of the Spanish Grand Prix.
