Sep.25 (GMM/Inautonews.com) Dr Helmut Marko was as cool as a cucumber on Sunday as Sebastian Vettel closes on the 2011 championship.

The German driver needs just a tenth place at Suzuka in two weeks to win his second successive world title.

And Vettel can only lose the championship if McLaren’s Jenson Button wins not only in Japan but also the four races after it.

That the Briton can do it is “not likely”, Red Bull consultant Marko told German television Sky in Singapore.

“In this field there is no one else strong enough to win the last five races,” added the Austrian.
