Gearbox fault consigns Rubens to back of grid.
Ferrari number two driver, Rubens Barrichello has admitted that he is 'very disappointed' after gearbox problems during qualifying meant he couldn't post a flying lap.
The Brazilian, who will now line-up last, reckoned that he could have been right up there with his team-mate, Michael Schumacher, who will start alongside pole-sitter, Jenson Button on the front row of the grid.
"All I can say is that I am very disappointed," said Barrichello.

Ferrari number two driver, Rubens Barrichello has admitted that he is 'very disappointed' after gearbox problems during qualifying meant he couldn't post a flying lap.

"All I can say is that I am very disappointed," said Barrichello.
"My car had a gearbox problem towards the end of my 'out' lap and I had to come back to the pits. It's a real shame, because I think I could have done well this afternoon.
"Now, I can expect to have to fight my way up the order in the race. It will be very tough, but as always, I will give it my all."
It wasn't the only gearbox issue Ferrari suffered Saturday either, as Schumacher's car also had problems during the morning's free practice. As such the team is currently 'assessing if the two failures have the same cause or not'.
"This qualifying session left us with mixed emotions," concluded team boss, Jean Todt. "On the one hand there is the satisfaction of seeing a Ferrari, Michael's, on the front row of the grid for the second time this season. On the other hand, there is disappointment that Rubens was unable to do a qualifying lap because of a gearbox problem. It was the second failure of this component today, after Michael suffered a failure at the end of the morning session. Now we have to analyse what happened to see if they both had the same fault or if they were two different problems.
"Starting from the back of the grid, Rubens has a difficult afternoon in prospect Sunday, but he has shown at other times this year that he is capable of making the best of this type of situation."
