Watch as Australia's bowling coach Craig McDermott says that getting the wickets of Alastair Cook and Kevin Pietersen on day two of the third Ashes Test in Perth was vital for his team.
Cook fell having worked hard to make 72 and Pietersen was dismissed trying to take on Peter Siddle on 19 and England went on to close the day on 180 for four in reply to Australia's 385.
McDermott paid tribute to Mitchell Johnson for taking a fine tumbling catch to dismiss Pietersen.
"It was a fantastic piece of athleticism really, great catch and a good wicket for us.
"The guys finished really well tonight. Those two last wickets in that last session (Cook and Pietersen) were very crucial, obviously to our day; and the last three and a half hours of bowling and fielding were superb.
"It was good tough Test cricket."
