Bill reports from Adelaide after day four of the Third Test as Australia post 349 and England mount a gritty response led by Zak Crawley and Joe Root. The target of 435 (never previously attained in Test history) was always going to be too much of a challenge but England can look back on the achievement (4 wickets) as some small positives. Travis Head's superb innings and Ben Stokes' bowling late in the Australian innings shaped the contest.
