I knew it would be challenging and I knew there would be stuff around the cricket, but not to this extent, Root said of the off-field issues that have followed his squad around Australia.I m fed up of talking about stuff thats not cricket. England trail the five-Test series 2-0 after losses in Brisbane and Adelaide. Australia can clinch the series with a win at the WACA ground in a match that will also mark England opener Alastair Cooks 150th Test.Only one team in Ashes history has rallied from 2-0 down to win the series: Don Bradmans Australia in 1936-37 at home.Root has faced more questions about the teams conduct and curfew than its cricket. Ben Stokes involvement in an incident outside a bar in England in September has resulted in the all-rounder being suspended from England duties while police determine whether charges will be laid.Recent alcohol-fuelled incidents involving wicketkeeper Jonny Bairstow and Ben Duckett, who is traveling with Englands second-tier squad, have only added to the focus on off-field issues.The latest episode, in which Duckett poured a drink on the head of veteran pace bowler James Anderson came on a night when team officials had relaxed a midnight curfew.Root, who took over the captaincy in July and led England in seven Tests against South Africa and the West Indies at home, is desperate to avoid a repeat of the series sweep on the last tour to Australia in 2013-14 and his urging his teammates to lift for one of the biggest games of our lives.
