Harris Siddle, Bird/Starc & Lyon isn't a bad test bowling attack at all, yet England are 3-0 up with only one batsman in form & having played to a fraction of their ability.
If England all play to their ability no other team can live with them. What happens when Cook, Trott & Prior get their form back, coupled with a non-injured KP & a born again Bell? All bowling attacks will be ground down & demolished.
With Anderson fully rested, Broad being reborn as the new Hadlee & a reanimated Steven Finn, I can't see Australia winning a single test in the return series. I'm confident in a 5-0 prediction to us.
