Champion Vettel speechless, Schumi proud

Sebastian Vettel was rendered almost speechless after a nailbiting Brazilian Grand Prix, which saw his sixth place finish after an early collision just enough to deny Fernando Alonso the title to complete his own hat-trick. \"This is really special. Right to the end I didn\'t know if I\'d done enough. Trundling along behind the safety car and then dragging over the line was just torture,\" Vettel gasped after the Red Bull driver won a third straight title at the age of just 25, having finished three points clear of Ferrari\'s Alonso. Regarding his opening lap collision which so nearly wrecked his race Vettel said: \"I just kept trying to race. We always believed. \"I don\'t know what more to say -- it was a crazy race,\" Vettel said. \"We could hardly have had more obstacles to overcome\" after the rain made conditions treacherous. Retiring seven-time champion, and Vettel mentor, Michael Schumacher praised his compatriot. \"I am very proud of Seb. I am very happy for him and it\'s good to leave the field open to him for further future success,\" said Schumacher.
