Question: Sebastian Vettel's once-promising title challenge is getting stuck - just like his Ferrari did during Sunday's Austrian Grand Prix. Vettel had high hopes of pushing for a fifth Formula One title after winning the second race of the season in Malaysia, but he has failed to finish on the podium in the past two races and trails championship leader Lewis Hamilton by 49 points. Vettel looked well set for third place at the Red Bull Ring circuit, until he pitted for new tires midway through the race. The change took far too long, with one of the mechanics struggling to fit the rear right wheel. Vettel could not catch Felipe Massa, who took third for an improving Williams team still hopeful of beating Ferrari in the constructors' battle.Nico Rosberg finished ahead of Mercedes team-mate Lewis Hamilton to win the Austrian Grand PrixSebastian Vettel had high hopes of pushing for a fifth Formula One titleThe German driver looked well set for third place in Sunday's raceVettel currently trails championship leader Lewis Hamilton by 49 points
