Berlin, Germany - Formula One fans want to see four-times world champion Sebastian Vettel lose to make Grand Prix races more appealing, F1 commercial supremo Bernie Ecclestone said in an interview on Wednesday.

The 83-year-old Ecclestone told German daily Bild: “Many people want to see Vettel lose because it would finally make the World Drivers' Championship more exciting again.”

Vettel will be looking to win his fifth consecutive world title when the season starts with the Australian Grand Prix on 16 March.

The German was booed at some races last season when he won 13 of the 19 races.

Vettel endured a tough final testing session in Bahrain last weekend when there were problems with the new Red Bull car.

He failed to complete a single lap in testing on Saturday due to electrical issues and problems with the car's Renault engine.

Williams' Felipe Massa posted the fastest time, clocking 1min 33.258, closely followed by Mercedes' Lewis Hamilton, who was just 0.06sec behind, while Vettel came in 18th fastest overall with team mate Daniel Ricciardo 10th.

Vettel blamed the new Renault engine for his woes, but Ecclestone refuted those claims, saying: “After all it allowed him to win the championship for the last four years.”
