England "shot themselves in the foot" with the pitch for the second Test, says former captain Michael Vaughan.
England were thought to have requested a slow surface at Lord's to negate the Australia fast bowlers and protect their 1-0 Ashes series lead.
But Australia won the toss and amassed 566-8, then dismissed England for 312.
"It hasn't been good for England or for cricket," Vaughan said. "It just gave Australia the opportunity to get that confident buzz back into the side."
The Australians, who lost the opening match of the series at Cardiff by 169 runs, opted not to enforce the follow-on at Lord's and added 108-0 with little alarm to extend their lead to 362 with two days remaining.
