David Warner breaks his silence on Mitchell Johnson row as Australia star explains meaning behind his celebration following century against Pakistan

David Warner has spoken publicly for the first time regarding the criticism he has copped from Mitchell Johnson after scoring a sumptuous century against Pakistan.

Warner was the recipient of huge criticism from Johnson ahead of the Test summer, with Australia's Ashes hero claiming the opener is not deserving of a farewell party due to his poor form and role in the sandpaper scandal.

But Warner hit back in the best way possible at Optus Stadium and celebrated by putting his hand to his mouth in what some fans felt was a dig at Johnson.

The 37-year-old explained the meaning behind his gesture - which he described as a 'nice little quiet hush' - at stumps.

'It's just anyone who wants to write stories about me and, you know, trying to use headlines get headlines, that stuff doesn't bother me. It's just the fact that I have to go out there, do what I have to do. And I'm allowed to celebrate how I want,' Warner said. 

Pat Cummins and Steve Smith have strongly defended their teammate in the press, and Warner went on to address the hottest topic in cricket.

'Mitch is entitled to his opinion. He's a former player. You saw Justin Langer's comments have said he's entitled to it. You can go back to Justin Langer's comments and refer to them, and so be it,' Warner said, in reference to an earlier Langer column in which he said former players should not comment on the current team.

News Corp reports that no reconciliation has been made between Warner and Johnson in recent days. 

Johnson was in the commentary box to watch Warner's stunning knock but refused to comment when approached by the media at the close of play.

He was asked on Triple M whether he felt Warner's direction was aimed at him. 

'Who knows?' Johnson said.

'He's got a hundred for his country.'

Johnson was keen to move on from the drama when he arrived at Optus Stadium.  

'Look, I wasn't meant to be here from what I was told,' Johnson said with regards to earlier reports that he had been dropped from Triple M's coverage.

'I was happy to be here. It has been an interesting time. I have given my opinion. I have said what I have said and we move on.'
