Australia's bowling coach Craig McDermott has said that Peter Siddle's dominance over Kevin Pietersen is playing on the mind of England's rock star batsman.
According to the Sydney Morning Herald, the Victorian quick dismissed Pietersen for the 10th time in his career and third in a row in these Ashes, late on Saturday in what could be one of the key moments of the series.
Completed via a wonder catch from Mitchell Johnson, who can seemingly do no wrong this summer, it left England ailing at 4-146 and Australia ever closer to the victory in Perth that will secure them a 3-0 Ashes win, the report said.
McDermott said that Siddle just bowls very tight lines to Pietersen and it plays on anybody's mind.
He added that some players don't like facing certain bowlers and some players don't like bowling to certain batsmen, adding that it has worked out in Siddle's favour.
