Paceman Mitchell Johnson says it's great to be back in the Australian team and that he feels that he can get back to his best form over the T20 and one-day series.

Aaron Finch's record-breaking innings saw Australia to a first competitive international win in 200 days as they beat England by 39 runs in the first Twenty20 international at Southampton on Thursday.

Australia opening bowlers Mitchell Johnson and Josh Hazlewood took four wickets between them as England slumped to 42 for four, with their side showing just two survivors from The Oval in Broad and Joe Root.

However, it was Root's commendable 90 not out — his first T20 international innings — off just 49 balls, including 13 fours and a six, that prevented a humiliating loss.
