Ghosn certain of Renault recovery

The reigning world champions have yet to finish on the podium in 2007 but hopes are high that Giancarlo Fisichella's fourth placed finish in Monaco is a sign that the corner has been turned.

And Ghosn, who says his company's future involvement in the sport is pretty much guaranteed by Renault being competitive, says that he has given no thought to what will happen if his team's fortune do not turn around.

"Well I'm not thinking at one moment about this hypothesis for a very simple reason," said Ghosn.

"I don't know why a team who twice, in the last two years, have won the double championship are all of a sudden not able to understand (the problem), make a diagnosis of the situation, make the modification, and react to it.

"And I would like to tell you the team is the same. The only thing that has changed is the tyre, that's all. The engineering is the same, the technical staff is the same, the management - everybody is the same. So I'm very confident."

Ghosn also believes that an improved car will also allow rookie Heikki Kovalainen to prove he is every bit as good as Lewis Hamilton.

"I think he has not had time to show his talent. And as Flavio (Briatore) has said before, he cannot blame the drivers on the fact that the car is still not adequate.

"But the car is coming. We understand what is going on, the car is going to be adapted and hopefully you are going to see the true performance of the drivers with a better car still this season. We are confident you will see the talent of Heikki later this season."

Team boss Briatore has expressed some frustrations at the lack of credit his team are being given this year, considering their success over the past two seasons.

"We talk about Renault, but we are among teams like McLaren-Mercedes who in nine years never won a championship, or Toyota who have never won a race, and Honda - who you don't know where they are.

"We are with the best people in the world. If you think about what Renault invested in respect of results then we are the world champions every year.

"When we started in 2001, our car was at the back of the grid. Everyone has such short memories that I want to give Prozac to somebody! We are an actor in this movie, but we are a good actor."
