Oz media says Johnson must remain 'cool killer' to 'keep striking' in Ashes

The Australian media has suggested that Mitchell Johnson should remain the same 'cool killer' if his side are to win back the Ashes against England in the Perth Test.

According to News.com.au, the key now for Australia is not to get carried away by all the verbal ferocity or their sudden success.

The rampant forces of form, ability and hunger should do the trick for Australia against a side who seems to lack that electric crackle of desperation that drove them to the top of the world, the report said.

Mitchell Johnson destroyed England three years ago in Perth when he was not the bowler he is today, the report added.

In five Tests in Perth he has taken 36 wickets at 19 and has never taken less than five wickets in a Test there, the report further said.

He can do it all again but he may have to revert back to being a cool killer for that is when he is at his best, the report mentioned.

Johnson went for 1-73 in the second innings after his 7-40 in the first and there were times on the fourth afternoon when England seemed to verbally challenge him and, while always dangerous, it was not his best work as the verbal stoush flowed back and forth, according to the report.
