Bernie Ecclestone insists that the 2014 season could provide Ferrari and Mercedes with the chance to topple Red Bull from its place at the top of the F1 standings.
Sebastian Vettel is odds on to take a fourth straight title on the back of his win in Singapore last weekend put him 60 points clear of Fernando Alonso, while Red Bull continues to lead the way in the constructors' championship.
Should he successfully wrap up the title, Vettel would join a select band of drivers to win four consecutive F1 titles but Ecclestone predicted that things could be very different in 2014, when new rules come into play in the sport.
"His [Vettel's] domination will end, maybe in 2014," the commercial rights holder told Bild
. "We're going to have completely new cars, new engines, new rules.
"That will be the chance for Ferrari and Mercedes to catch up with Vettel. Next year, it might not be the best driver but the best car that wins the title."
Ecclestone also made comment on the booing that Vettel has faced on a number of occasions this season, saying it was the German's dominance that was leading people to jeer him on the podium.
"He doesn't give Fernando Alonso and Lewis Hamilton a chance," he said. "He's as dominant as Senna or Schumacher in certain periods."
