Lauda said that with Vettel ahead in the championship it is only a matter of time before he takes yet another world title.
"I would go so far as to say Vettel will be the world champion in Abu Dhabi, which is the third to last race," Lauda told Bild.
"His points lead was already big when he dominated at Spa, even though the Red Bull is not really suited to this track. Ok, maybe for Monza he is not the favourite, but on every other circuit he has the best car. It is more than enough for him."
Vettel has won the championship for the past three seasons.
