Ashes 2017/18: 4th Test, Day 1, 5 things we learnt from the day

#1 Steven Smith just can't stop scoring

There is no better Test batsman in World cricket at the moment

Steven Smith's hunger for runs has no end. The Australian skipper is on a marathon at the moment and it doesn't look like it will stop till he crosses a batting average of 70. Nudging, flicking, driving, stepping out, pulling...you name it, he plays it without breaking a bead of sweat.

Smith bludgeoned his way past England's post-lunch session and made the post-tea session a traumatic one for Root's men. The Aussie skipper was at his flamboyant best, constantly rotating the strike, finding the odd boundary and putting England in a fix. That he looks well set for another hundred would be England's biggest worry heading into day 2.
