Whatever England's best performance has been in this World Cup - and that is hard to gauge given their level of inconsistency - they were well below it in Chittagong and deserved to lose to a spirited Bangladesh.
They looked petulant and grumpy in the field, complaining about the ball being wet because of the dew, which does happen a lot out here.
The thing was the damp conditions had a positive effect, they made the ball grip and enabled England to take wickets.
But James Anderson looked haunted and drained. His eyes looked blank, as if he had nothing left to give.
I have been banging on about this for some time now and maybe one day the authorities might take note, but you cannot keep sending teams all over the world for months on end and expect them to play high-intensity cricket.
Frustrated Strauss still hopeful of qualification
Apart from four days at home they have been on the road for nearly six months now and they will have been listening to the same coaches and doing the same fielding drills for all this time - they are probably sick of the sight of each other!
You could tell by their attitude towards the end of this match, they were tetchy and looked as though they had had enough.
The question is whether Andy Flower and Andrew Strauss can lift them for one more huge slog up the hill?
It is easy to get up for the big games, against the best players, in front of big crowds, but against the lesser teams it is much harder to keep lifting yourself and almost inevitable it will not happen as you are drawing from the same well.
Look at Ian Bell, who made only five from 23 balls. He hasn't batted anything like the way we all know he can and looks so far removed from the stylish batsman we all enjoyed watching in the Ashes.
Now it is on to a crucial match against West Indies in Chennai on Thursday and you get the feeling West Indies have a decent performance around the corner with the way they play.
Darren Sammy has been a decent captain and Kemar Roach has bowled fast but England should go into the match as favourites having already played there and played on similarly lifeless pitches for a fortnight.
The Bangladesh fans celebrated their win in fine style
Dare England risk Anderson? To see him firing those wides down the leg side was very sad and so out of character. He looked so far removed from the man who led the attack so magnificently in the Ashes.
It would be a very brave call to leave him out of a must-win match though. It's easy to say from afar that he should be dropped after that performance (0-54 from nine overs) but who are you going to replace him with? Chris Tremlett, who has not played in the tournament?
I still think most people would want to see Anderson running in but he's going to have to find something from somewhere.
Ajmal Shahzad had a difficult start against Bangladesh but produced some really good balls. He's fresh you see, he hasn't been slogging around all over the place. He is a lively character, always nipping at your heels, he can bat as well and I like him.
I also quite liked Paul Collingwood at number seven because I don't see Michael Yardy playing a positive role. Yes he can bowl tidily but England want more than that from their spinners and Collingwood can bowl his cutters, he is still a capable batsman to provide depth lower down the order and he fields brilliantly.
Whatever England's shortcomings it was great to see the sheer delight on the faces of the Bangladesh supporters and the ground staff doing a lap of honour.
Everywhere you look here you see children playing cricket on dusty roads, just enjoying the game, and hopefully that is the legacy this World Cup will leave.
