'A 22-year-old playing in the Under-15s'

If England didn't already know about how strong Australia's attack is, Mitchell Starc sent out a reminder with two hat-tricks in one Sheffield Shield game. The man whose role Starc hopes to emulate in the Ashes led the plaudits for the incredible feat.

Before his double-hat-trick this week, Starc took a career-best 8-73 in the second innings of his previous Shield game.

England commentators looked to play down Starc's red-hot form.

Others set even higher targets for Starc.

Much higher targets.
