Congratulations Australia - you boys gave us one hell of a beating. You're looking menacing, but thankfully it's still 1-1.
On that note, I think it's not panicking to change at least 2 batters who seem woefully out of nick and confidence - we have a series to win here. As much as I am not a Bell fan, I would keep him in and swap out Lyth and Ballance. Compton to open anyone?
If Wood is not fully fit, then he;s out - but don't try and replicate the Aussies by bringing in left-field Footitt. Just pick the next guy off the rank who's in form. I wouldn't mind Brooks getting a shout.
Oh, for a decent spinner - I do fear for Ali long-term. Come on you young English tweakers, there' a place to be had!
