LONDON, England - Red Bull's Daniel Ricciardo believes Formula 1 drivers should respect team orders unless they are "completely out of order".Vettel made his dissatisfaction clear at the April 2014 Chinese GP after being told for the second race in a row to let Ricciardo overtake because he was faster.Vettel initially said "tough luck" on the team radio before Ricciardo made it through three laps later to finish fourth ahead of Vettel in fifth.'OUT OF ORDER'Ricciardo has out-qualified quadruple champion Vettel ahead of three of the four races in 2014 and team orders could again come into play if Vettel gets in front of him at the 2014 Spanish GP.Ricciardo said: "We throw up different scenarios and discuss it - discuss it between drivers, principals and engineers. It is our responsibility to obey unless it's completely out of order and then we can try to put up a fight and give our reasons."Despite a superb start to the season, the disqualification that robbed him of second at his home race in the season-opener, has left Ricciardo sixth in the title race. Vettel is fifth.Vettel's relationship with former team mate Mark Webber, who never doubted which of them was Red Bull's No.1 driver, was poisoned when he overtook Webber to win in Malaysia in 2013 despite being told to hold his position.Ricciardo thinks that while he and Vettel are both highly competitive they will continue to show each other respect no matter how the season pans out.Ricciardo said: "We know it ourselves and even told each other that we want to race hard. I want to race the best version of Seb and he wants to race the best version of me. I think we'll both respect whoever does the better job."I think that's a two-way street. We understand what a fair fight is and we enjoy that."Stay with Wheels24 for the 2014 Spanish F1 GP weekend.
