During the last Ashes series, the Australian openers were also in the same condition. David Warner hardly went past single digits during the entire series. But we all know how the series ended up. Steve Smith and Marnus Labuschagne neutralized their weakness in the top order. In case of England this time, Malan and Root have been scoring runs, but they are not scoring enough runs to make it up for the off-form players. The roles seems to have completely reversed between 2019 and 2021, but England seems to be in a worse position when compared to Australia in 2019.
Australia are in habit of winning with big margins. Last time they whitewashed England was in 2013/14 5-0 and the way things are going I am sure Australians have worked hard for 5-0 this time also. 2019 Ashes was balanced, as both sides won 2 matches and one game was draw. Before Series England was favorite but during the series odds went in favour of Australia.
