Not sure who else they could have picked to be honest, Finch deserves a shot in the white clothes, Mitch Marsh is comfortably the best all-rounder Australia has currently, and Peter Siddle is coming off some incredible form in county cricket and adds a degree of experience and leadership.
I can't help but Head and Labuschagne are gut instinct selections, and why not, a fairly trivial UAE series that will fly under most radars is the perfect time to follow some hunches, both can bowl handy part time spin as well apparently.
