Australia's pace-man Mitchell Johnson would like to concentrate on his Test career by quitting from at least one format of international cricket.

The 32-year-old left-arm fast bowler made an impressive finish in the tour of South Africa, conceding 22-wickets to help Australia secure the test match series by 2-1.

Johnson also made a formidable comeback in Test cricket during Ashes, when the Aussies nailed England by 5 - 0 in the series.

Johnson, however, suffered from toe infection after the end of the South Africa series, further leading to his unavailability in the T20 World Cup held at Bangladesh.

When asked if he would be comfortable with all the format of International Cricket, he replied, "Probably not."

"I think I've got to be a lot smarter now ... Twenty20 cricket you don't play a lot of anyway, it just happened at this time there was a World Cup straight after the South Africa series which I was looking forward to being involved in before I got injured ... Twenty20, I will quite happily say, is not my favourite format - I would rather play Test cricket ... And maybe one day (international) cricket I have to look at as well," read parts of Johnson's statement on Australia Cricket's Web site.

Though Johnson is trying to move away from the smaller format, he is rather keen to be a part of World Cup squad, as Australia will host the 2015 ICC World Cup.

Johnson was also a member of the 2007 World Cup squad at West Indies, but he remains in the stand without playing any match.

"I'd like to win a World Cup - I've been involved in the West Indies in 2007 which was a well-paid holiday apparently ... so I would love to be a part of Australia's 2015 World Cup and I certainly think we've got the team to win it ... We've played some really good one-day cricket and given that it's being played at home, it would be a great opportunity ... But my main goal now is to get to that 2015 Ashes series in England, so I'll be doing everything I can to reach that goal," Johnson added.
