England captain Kevin Pietersen said his team had been taught "a few quick lessons" after being thrashed by 124 runs by a club side in Mumbai.
They were dismissed for just 98 three days before the first of seven one-day internationals against India.
However, Pietersen insisted nothing should be read into England's display.
"I'm not sure if we were fully focused but this is a really good lesson. I don't see this is a bad thing. I think the guys are all right," he said.
"The wicket wasn't difficult. We didn't apply ourselves as we should have. I think there was just a bit of indiscipline in some of the shots and some of that just crept in.
It's Friday that counts for us now and we will be coming real, real hard on Friday. It's a big, big series for us
"What counts is the internationals We just need to turn our heads on now and make sure we start on Friday. Today doesn't really count in the grand scheme of things."
The disappointing display even prompted coach Peter Moores to order the England players back in the middle for a practice session, usually known as "naughty boy nets", immediately after the match.
Tuesday's display was in stark contrast to England's 122-run victory over a Mumbai Cricket Association side on Sunday and highlights the scale of the task ahead of them as they attempt to win their first one-day series in India since 1983-84.
The hosts had made 222-7 against an England bowling attack missing Stuart Broad, withdrawn for precautionary measures because of a sore knee, and Ryan Sidebottom who is still struggling for fitness with Achilles problems.
Pietersen's side lost their first six wickets for 38 runs in reply and were 55-8 before Graeme Swann (24 not out) and James Anderson (20) put on 34 for the last wicket.
Pietersen, who has scored 6 and 0 in India so far, admitted his side was rusty but was confident his side would improve in the first one-day international against in Rajkot on Friday.
"We played our last competitive game before the Stanford week, round about 3-4 September," he said.
"That was a long time ago. We had a good seven weeks off into that week. And now we are back into the real, real tough stuff to come here to India.
"It's Friday that counts for us now and we will be coming real, real hard on Friday. It's a big, big series for us."
England have either won spectacularly or folded dramatically in the short time they have been led by Pietersen.
When hauled in at short notice to replace the suspended Paul Collingwood in the final one-day international against New Zealand in late June, he presided over a 51-run defeat.
But when taking the captaincy full-time after Michael Vaughan's resignation he enjoyed a honeymoon period in which the team won the last Test against South Africa, then beat those opponents 4-0 in one-day matches.
But in the $20m Stanford finale on 1 November, England were bowled out for 99 by the Stanford Superstars to be thrashed by 10 wickets.
