FORMER Australian skipper Allan Border has instructed Test enigma Mitchell Johnson to ''bust some English heads'' in the first Ashes Test, which starts on Thursday.
And Border - nicknamed Captain Grumpy - also urged the underdog Australians to immediately cease any friendliness with the Poms.
Johnson has the aggression and intimidation to rattle cocky England according to Border, who played 156 Tests.
"That's what I would be telling him. And don't worry about runs per over. Just go out there and let rip.
"Mitchell has that fear factor. There are moments when you think if Mitchell gets it right, he could cause some real headaches.
"I think he is a stronger character going into this series, his action looks good and he is bowling with good pace. You can't buy that stuff on a shelf.
"I wouldn't care if he went for five or six runs a over. I would want him to run in and bowl rapid.
"I have good feel about Mitchell going into the Test series. I like his selection - he is a bit of an x-factor.
"Mitchell has be a bit wayward at times but if he is 'on' , he can ruffle a few feathers bowling at that pace.
Border famously snubbed English players during Australia's 4-0 Ashes win in 1989.
"Particularly when you are on the threshold of losing four (Ashes) in a row. All that mateship goes straight out the window as far as I'm concerned.
"The 'chummy-chummy' stuff, I reckon you can put that on the backburner for three or four months.
"Make no mistakes, England aren't chummy out on the field either. They went through a period where they lost eight series in a row.
Australia will start the series firm underdogs although Border is confident.
"England deserve to be favourites but I think our side is on the rise,'' he said.
"The first game in Brisbane is crucial. They are conditions we know and should play well in.
