He had a very slow puncture on a rear tyre. That lost him a lot of time coming back to the pits, AND doing the ill-timed pit-stop.
Also, it affected the rear differential a lot, which led to the team adding too much front wing.
Then the balance of the car was all out of whack.
Jenson button drove an amazing race, it’s true.
But any talk of Button somehow magically surpassing Hamilton is rubbish.
Lewis is still the better driver, and will prove that again in the following races this year, and next year also.
As long as McLaren can actually give him a good qualifying.
There was no reason for him to be even sent out that late for a second run in Q3 on the Saturday.
They screwed up again and again, just like in Monaco, just like in Malaysia 2010, like Italy 2008 and Italy 2010 (put him out RIGHT behind Webber), to name a few off the top of my head.
McLaren badly need to work on their Q3 strategies and never just leave it too late, it’s so simple!
