Ashes 2017/18, 2nd Test: 5 things we learnt from the second day's play

#1 England under immense pressure

Cook will be a vital player for England if they are to stage a comeback

Conceding 442 in the first innings of a day-night Test, England are forced to play catch up game. Rant can go on about how Root should ideally have batted first or how the English bowlers should have bowled more at the stumps. But they have to forget the past and start worrying about getting close to the Australian total.

Alastair Cook, who has so far remained vulnerable at the crease in Australia, will be a crucial player for England on the third day. The last (and only) time he played in a day-night Test, against West Indies, Cook slammed a double hundred. If he can anchor England's fightback, Australia may have their task cut out. But at the moment, the hosts appear well and truly on top.
