Ross Brawn admits he has been "very impressed" with Jenson Button's driving in the first two grands prix of the 2009 season.
The British driver scored an emphatic win from pole position at the Australian Grand Prix last Sunday, and kept his momentum going today by securing his fourth career pole in Malaysia.
Button endured a dismal 2008 season with Honda Racing, scoring just three points, but things have looked much brighter in the team's re-incarnation as Brawn GP.
"Very," said Brawn when asked how impressed he was with Button. "I don't think last year with the equipment he had... I commented a few times, I saw some good races, I saw some races that were not great.
"You know him, you can see he is revelling in it and he is driving very well. He is such a smooth driver it is incredible."
Brawn added: "He is working very diligently with the engineers and he has been kind of revitalised and that is understandable, if you have got some equipment you can use.
"I think the car is hopefully going to get better over the next few months and he is going to naturally improve because he is hugely talented and two years of beating your head against the wall takes it out of anyone.
"I think we were very impressed today, he never put a wheel wrong. His times on the prime tyres in the middle of qualifying were just stunning."
Button, who was linked with the Ferrari team when Brawn was there, that overlooking the Briton's talent while he was there may have been an oversight.
"That might have been a mistake," he said. "It's just so difficult to judge people. I mean Jenson is a pretty low profile guy in many ways. He doesn't bang his own drum and he gets on with things discreetly and quietly.
"It's a bit like his driving style, very smooth and very controlled so I am very happy."
