People have said I struggled to swing the new ball but I wasn't conscious of that myself. We knew that the Kookaburra stops swinging quickly and conditions need to be just right for it to go.
I was simply not accurate enough over a long enough period and my third and fourth spells were not up to the standard I set myself.
One of the key factors in our success in 2010-11 was the big runs our batsmen made in the first innings. That allowed us to rest.
