The Italian thinks that it will take too much time for Brawn GP, Toyota and Williams's rivals to catch up with the diffuser gang and has questioned the credibility of the the world championship because of it.

"The drivers in our teams have been and are world champions, while the championship is now fought between a driver who was almost retired and another one who is a good guy but a paracarro (Italian saying for being as slow as a milepost at the side of a road)," Briatore told Gazzetta dello Sport. "I don't know where credibility has ended up with all this. To make up the gap we have to those teams is impossible."
