"Australia win, Johnson struggles": not my words but the Cricinfo report headline of the Australian team's three day game v Northamptonshire. Couldn't have put it better myself.
Stuart Clark, Shane Watson and Andrew McDonald all turned in good performanceswhile in the second innings Graham Manou redeemed his first innings golden duck Australian debut with a robust unbeaten half century. Clark surely deserves to play in T3 and Watson must also be in the selectors' minds (but with his history of injuries perhaps not in the forefront thereof) . McDonald probably won't be considered even though in each Test he's played he's performed above expectations.
Which is more than can be said for Mitchell Johnson....
I think he should be dropped.
