Sydney, Aug.27 (ANI): Former Australian fast bowler Glenn McGrath has told left-arm quick Mitchell Johnson not to overdo or over think things and keep things simple if he wants to reach his considerable potential as a Test match bowler.

McGrath, who has high hopes for Johnson and the other two members of Australia’s Ashes pace attack - Ben Hilfenhaus and Peter Siddle, feels Johnson’s potential, will be reached only through a clear head uncluttered by countless theories about his bowling technique.

Though finishing with a solid return of 20 wickets at 32 in the Ashes series, Johnson was not the rampant force he was in South Africa and earlier at home.

“All his problems were sorted out when Michael Clarke said to him ‘just bowl fast’,” McGrath said.

“I can understand that. He needs to keep it simple. That is the key. He just has to clear his head and not complicate things. Less things can go wrong when you keep it simple. I just used to switch a voice off in my head, pick out a song to sing at the top of my mark and trust myself that my body knew how to bowl. It didn’t always work. But if you win the battle with yourself you are 75 per cent towards being successful,” the Courier Mail quoted McGrath, as saying.

“That’s all Mitch needs to do. Just relax. Even when he isn’t bowling well he still takes wickets. It is just a confidence thing. He needs to just run in and bowl,” he added.

McGrath also felt that Brett Lee can again return as a Test match force for Australia but the Johnson-Siddle-Hilfenhaus union has the potential to be a long-term one for Australia.

“Those three guys will grow as time goes on. They were the leading wicket-takers in the Ashes from both teams. You can’t really sledge them too much because I think they have done pretty well,” he said.

McGrath said Lee bowled well in an early tour game before being injured and cannot be dismissed from Test match calculations this summer when Australia play the West Indies and Pakistan in three-Test series. (ANI)
