MELBOURNE, Australia - Felipe Massa has kicked off the next phase of his Formula 1 career with two thumbs up - one of them for his move to Williams.Despite the British team finishing the 2013 season deeply uncompetitive he has found himself powered by a plum Mercedes engine."I am happy, that's true," the Brazilian, who lost his Ferrari seat after eight years to Kimi Raikkonen, told German newspaper Bild. "I'm glad I went this way. It could have been a stroke of luck. The car feels good."NEW LEADER?Massa's other sky-pointing thumb is for the end of the Ferrari era where, despite intense highs and the almost title-winning 2008 season, the 32-year-old experienced some deep lows.Asked by correspondent Nicola Pohl to describe what four years as Fernando Alonso's 'water-carrier' felt like, he answered: "I'll tell you one thing. The time as a servant is over! Williams wants me to take a leadership role in the team."In a team you sometimes have to do things that you don't understand at that moment but you're not a racing driver if you cannot win."Stay with Wheels24 for the 2014 F1 season – fresh reports every day.
