1. Magic Johnson
England have never really seen the best of Mitchell Johnson. He ended up with 20 wickets in the last Ashes series, but by no stretch did he bowl anything approaching well. Today he was simply unplayable. Pace, dramatic late swing and, most surprising of all, accuracy. There would normally be plenty of blame attached to the batting side in a collapse as monumental as England's, but on this occasion you really do just have to give credit to the bowler. Just too good. The deliveries that got Jonathan Trott and Kevin Pietersen - neither man in dodgy form -would have dismissed any right-handers in world cricket, while Collingwood lbw b Johnson was the single most inevitable scorebook entry since records began. After his initial four-wicket burst he returned to mop up the tail and secure figures of 6-38 that were as accurate a reflection of his efforts as 0-170 was in Brisbane. An astonishing turnaround.

2. Ryan Mighty
Mitchell will inevitably and correctly attract all the plaudits, but Ryan Harris was superb again. His three wickets were just reward for his endeavours both here and in Adelaide where he carried a woeful attack single-handed, and it's worth noting that his scalps included the only two England batsmen who hung around long enough to look dangerous as Andrew Strauss nicked a beauty and Ian Bell chased a wide one.

3. Point Of Order
And why was Ian Bell chasing a wide one? Because he was batting with the tail. Again. If Ian Chappell's view that Bell should return to settle his score with the number-three position is perhaps overstating the case, then promotion to number five is already overdue. A batsman of Bell's class batting at six is like keeping a Van Gogh in the basement. Just as Australia must send Brad Haddin in when the next wicket falls tomorrow, so England must make an immediate move to rectify the glaring error in their own batting order.

4. Pitch Battle
Much talk of how refreshing it's been to see Test cricket played on a pitch that offers everyone some help. While this Perth pitch has indeed been a good one for entertaining cricket, I'm not sure how much credit/blame it can actually take for Australia's top order batting like novices or Mitchell Johnson defying the laws of physics.

5. Test Pass
What today's play has confirmed beyond any wrong-headed doubts anyone may entertain is that Test cricket is mankind's single greatest achievement. The dizzying speed with which a slow-burning storyline can explode into life, the way preconceptions can be turned on their head, and the glorious unpredictability of a seemingly obvious narrative arc is unmatched anywhere in sport, theatre, literature or art. It is wonderful.
