Daniel Ricciardo says Sunday's Chinese Grand Prix victory alone is not enough to convince him to stay at Red Bull next season.
Ricciardo's current contract is up at the end of the season and for the first time in his career he will be free to explore options at other teams without Red Bull having the ultimate say over his next move. He went into this year's championship hoping to challenge for the title but has made no secret of his desire to keep his options open for 2019 if Red Bull fails to perform.
His victory at last weekend's Chinese Grand Prix propelled Ricciardo to fourth in the drivers' standings, 17 points adrift of championship leader Sebastian Vettel, but after a series of reliability issues in the opening two races he says there is more to do to convince him to stay at Red Bull in 2019.
