He wanna means Ted Kravitz from BBC:
"...McLaren had their Bahrain aerodynamic package on for the last two days of the test and the car enjoyed a significant improvement.
Hamilton happy with McLaren progress
The updates delivered what the wind tunnel suggested they would, which is always a relief for any team with a new car.
Jenson Button ran a race simulation with the new package on Saturday but did not have the set-up he wanted on the car, so his times didn't compare too well with Ferrari's Felipe Massa, who was also doing a race run at the same time, or his McLaren team-mate Lewis Hamilton, who did a race simulation on Sunday.
McLaren engineers have been investing a lot of time in tyre management - a key component this year as most races will be done on a one-stop strategy following the banning of in-race refuelling.
Success in the first few races will come from being easy on the tyres and keeping them in good shape. In short, McLaren are not where they want to be yet, but they're close and they believe they'll get there..."
