Root glanced Australia fast bowler Scott Boland for four runs down the leg side to complete his 40th test century off 181 deliveries, sparking loud applause from the England supporters at the Gabba.

The 34-year-old's previous best in his 16 Ashes matches in Australia was 89 before arriving in Brisbane.

Root's century was crucial in rescuing England from early difficulties after they lost two wickets for five runs in the third over of the pink-ball test at the Gabba, both taken by Mitchell Starc.
