Really? If not now , then when? Against Bhutan?
Rest are excuses. He is the captain and made a lousy toss decision. He should get to know his team better.
Against Bhutan would be nice

Most away series the home team is likely to win. Overcoming that odds and beating the opponent team requires a team which is firing on all cylinders and a very good captain. I feel that England have the latter but the former is not happening. Missing out on star players and fielding lapse is dragging them down.
Toss wasn't a bad call. There was a bit of swing and I guess he wanted to make early inroads into the Aussie batting.
Getting to know the team better - This is something Root can improve on. Being England's captain is not an easy task. Given the history with Cook & KP saga, you never know what is the stress level for Root as a captain
