Briton was fastest in testing in Spain.
McLaren made a promising start to the new F1 season when driver Jenson Button topped the times on the first day of pre-season testing at Jerez.
“This morning was boring really,” said Button.
There are still British GP tickets available for this year’s race at Silverstone
“I was sat in the office – sorry – sat in my motor home all morning. These guys (mechanics) were all working flat out to fix the fuel pump issue that we had and (we were) able to get out at about two o’clock and put some good laps in.
“But it’s always tricky when you have to wait so long and everyone else is flying around doing laps and seeing what the car can do whilst you are sat around doing nothing.
“But it was good to get out in the afternoon and do some brakes work and do some flo-vis work. So you can really work out if the aero (aerodynamics) are working correctly, and also to do some runs, and get a feel for the car and yeah, I have a good feeling with the car and it doesn’t feel like there is anything that scares me about it. I feel very at home within the car.
“The feeling is nice with the car and it is a good base for the first test so, we will see. But there are a lot of test days before the first race, the cars are all going to look very different by the time we arrive in Melbourne, so you can’t look at the times (lap times).
“All you can do is go by feel and develop the car in the direction that feels correct to you.”
