Li ignores coach's orders, still wins

China's Li Na has revealed she ignored her coach's orders to block out memories of her good form on grass as she marched into the last eight at Wimbledon.

Li knocked out Poland's Agnieszka Radwanska 6-3, 6-2 on Monday to claim a place in the quarterfinals and exact revenge for her exit to the same player last year.

Li went out in the third round 12 months ago, beaten in straight sets by the Pole, on the same Court 18 that she won on this time around.
