Barrichello: Senna will have F1 future

After conceding that his huge experience in F1, having made 267 starts, was a key factor in helping him get the seat, Barrichello believes that Senna's talent will still be enough to eventually see him make it all the way to F1.

"I left a message on his answer machine. We are good friends and although we haven't talked for the past few months and it is sheer coincidence that we ended up fighting for position," Barrichello said. "I wish him all the very best, for someone who has only four years of experience he has done fantastically well.

"He has a future in F1 for sure. I haven't seen anyone just yet with the capability of having run four years in cars, and all of a sudden getting to F1 and doing so well like he did in testing. I am just lucky that at this time F1 changed a little bit and because of a lack of testing it is going to more experienced driving again - but I wish him all the very best."

Button set the fourth quickest time of today's test at Barcelona in the Brawn GP car, and after watching the development of the car over the last six months, Barrichello believes the team will be competitive in 2009 and says he only agreed to return to F1 to win races.

"I am only back to win," he said. "It has been a tough two or three years and I am not here to promise anything, but I am only here competing because I feel I have the chance to win.

"It would not be my desire to just come in and compete with something that I did not think was good just to make up the numbers. I knew what the car was coming to - the good numbers on the aerodynamics and everything made me feel that I could still compete on a higher level and go to win. So I have to dream every day to wake up and do that, and I feel that that is very, very possible.

"I must congratulate the whole team for the effort since this car was started in May/June last year. We knew aerodynamically that the car had all the potential to be strong, so today is only a good proof of that. We are delighted that the car is running reliably and I am so pleased I am going to be driving it tomorrow."
