as good as bichel is he is not brett lee. fair enough dropping him for queensland and perhaps even adelaide but if lee is fit, confident and taking wickets i would select him over bichel everyday of the week.
lee is in a different class to bichel and on the waca wicket he will be frightening. it was only ever a matter of lee performing well to get his place back not bichel doing badly.
as for Lehmann, he's had 3 digs, IF he gets another in this test and fails he may be struggling. martin loveshould get the chance at increasing his 450no in 2 innings against the poms. after that its anyones guess.
