Daniel Ricciardo says he needs more than winning last Sunday’s Chinese Grand Prix to convince him to stay with Red Bull next season.

Daniel Ricciardo has called on Red Bull to deliver a championship-winning statement of intent at Formula One’s season-opening Australian Grand Prix — but fears Lewis Hamilton’s Mercedes team will still be the sport’s leading force.

Sebastian Vettel was accused of deliberately driving into his title rival Lewis Hamilton as this year's Formula One championship burst into life during a dramatic Azerbaijan Grand Prix.

Hamilton also benefitted from a disastrous pit-stop gaffe by Daniel Ricciardo's Red Bull team.
