World motor racing chief Max Mosley is fed up with rival teams moaning about Ferrari's dominance of Formula One.
Mosley has criticised teams for not being competitive enough
The Italian team have won six constructors' titles in a row and Mosley said this was down to the competition not being good enough.
"Ferrari aren't killing the sport. I'd say Williams, McLaren and to a lesser extent Renault and BAR are because they're doing a rubbish job," he said.
"It's not up to Ferrari to lose, it's up to the others to win."
But he also played down fears of a breakaway alternative world championship, with Renault, McLaren and Williams tied to the Grand Prix World Championship (GPWC) group, whilst Ferrari are signed up with Bernie Ecclestone.
"I don't think there will ever be two championships. The reality is that sooner or later it will be sorted out" he said.
"The difference between Bernie and the GPWC is that Bernie has contracts with promoters, with television companies and with Ferrari which go beyond 2008."
Mosley insisted the future of the sport was bright, and said the sale of Jaguar and Jordan to new owners was proof of its financial health.
"It looks healthier than I can remember because of those two people coming in," said Mosley.
"We had a big crisis in Japan, China and Brazil when two teams were on the point of going out of business and two more were in danger.
"But the financial crisis which was threatened last autumn has disappeared."
And he says a new offer from Ecclestone from 2008 will make F1 teams even better off.
"In 2008 the teams are effectively going to get 50% of the entire income of Bernie's companies," he said
"That is a substantial income and in addition from 2008 there will be backdated payments for the years 2004, 2005, 2006 and 2007 which will be spread over the five years of the new agreement.
"It's somewhere between 500million dollars and a billion to be shared out between the teams.
"It will certainly be significant."
