Fast bowler Mitchell Johnson admits the pressure of leading the Australian attack in the Ashes cricket series against England got to him.
Johnson went into the series as Australia's trump card after strong performances against South Africa earlier in the year but has failed to make an impression.
The left-hander struggled with his line and length in the first two tests at Cardiff and Lord's but finally rediscovered his rhythm at Edgbaston and then Headingly as the Australians levelled the series at 1-1.
Johnson was heavily criticised for his wayward start to the series and feared he'd be dropped.
Australian media had speculated that the cause of Johnson's problem was a public falling out with his mother but the paceman insists that wasn't the case.
He says personal issues don't affect him when he's out on the pitch as he simply goes out there to play cricket.
