"We have had two disappointing games and we haven't played well enough in both games, and we know that," said Moores.
"So it's a chance again to come back and play better. In two or three different areas of the game we haven't really played as well as we wanted to."
The hosts struggled against spin at Nottingham where the Indian slow bowlers strangled them with six wickets. Even in Cardiff, the Indian medium pacers had made initial breakthroughs. This happened despite England's new opening combination of Alastair Cook and Alex Hales giving them two 50-plus stands in successive matches.
"We've got some good players of spin, in that side the players like Ian Bell, Alastair Cook and Eoin Morgan, who are good players of spin. But we have to deliver in a one-day game and that, to me, is partly about skill and partly a mindset, which is something that obviously goes with the territory of the job of being a one-day international player," he added.
"I don't mind people having a view. It's probably healthy people have got a view on what they think is right and wrong. The key for the players is they've got a chance to make a difference, because they're in there and they're doing it. We have to get the right score and there are different ways of getting it.
