Ashley Giles believes his old captain Michael Vaughan tweeted harshly and "in haste" that a partial ticket refund should be in order after England rested five first-choice players for the NatWest Series.
A team minus captain Alastair Cook, his one-day international opening partner Ian Bell and frontline bowlers James Anderson, Stuart Broad and Graeme Swann came unstuck in an 88-run defeat against Australia at Old Trafford.
The same experimental line-up, give or take the possible inclusion of one emerging player for another under stand-in captain Eoin Morgan, must therefore try to battle back from 1-0 down with three to play at Edgbaston.
Vaughan responded to the announcement of England's squad, and before Australia went on to pile up 315 for seven in Manchester against an attack featuring only three tried-and-tested specialist bowlers, by calling for a minor reimbursement for anyone who thought the event might have been mis-sold.
Asked about the opinion voiced by his former Test captain, England's limited-overs coach said: "It's harsh - I think it was said in haste by Michael."
Giles can hardly argue over the absence of almost half the team who can reasonably be expected to represent England at the next World Cup in Australia and New Zealand in 2015, but added nonetheless: "This is an exciting side to come and watch.
"(There's) Kevin Pietersen; Michael Carberry is an exciting batsman at the top of the order; then you go (Jonathan) Trott, (Joe) Root, Morgan, (Ravi) Bopara ... (Steven) Finn - there are some good names to watch.
"Then you have the youngsters.
"I'd hope the cricketing public would want us to bring through some of our young cricketers and expose them to what is almost the harshest of environments, which is playing Australia."
Among those tasked with doing that at Old Trafford was Ben Stokes, deployed as a bowling all-rounder at number eight - a pivotal role England will hope Tim Bresnan can reprise once he has recovered from a stress fracture in his back.
Giles acknowledges it is a tough challenge for a raw talent, but is confident Stokes - and others in his squad - have great potential.
"You don't get ready-made replacements for Broad, Bresnan, Anderson," he said. "So this exposure is crucial.
"It's hard on these young guys at times because we're asking them to do a lot.
"But we're asking them to do it because we believe they can.
"If this exposure goes the right way, we've got a much greater pool of players to look at for 2015.
"We just never know what's round the corner - whether it be injury, retirements in some cases - so we have to be prepared for everything."
