Mitchell Johnson signs for Perth Scorchers in Big Bash League

Former Australia paceman Mitchell Johnson has signed for Perth Scorchers in the Big Bash League.

Johnson, who retired from international cricket last year, has never played in the tournament and the 34-year-old said he was hoping to mentor some of the nation's young talent. 

"I want to be involved in the coaching side of things, which has become a bit more of a focus for me," he said.

"I was never going anywhere else and always wanted to stay here and be part of the community. To be able to play for the Perth Scorchers, where I live and where I'm based, is perfect for me."

In announcing his retirement in November, Johnson, who played 73 Tests, 153 ODIs and 30 T20 games for Australia, said he no longer enjoyed the challenges of the tough days in the field.

"It was a little bit physical, but it was more the mental side of things, I had just had enough," he said of his decision.

"I felt I couldn't compete at this level any more - on those tough days, I didn't want to be there."
