Andy Flower is adamant that England have not achieved enough to be in any danger of becoming complacent after their crushing win in Adelaide.

Flower saw his side complete their biggest victory Down Under for 40 years as England pummeled Australia by an innings and 71 runs in the second Ashes Test.

Despite the one-sided nature of the match and subsequent talk that the rest of the series could be something of a formality, the England coach has snuffed out any suggestion that his side are about to take their dominance for granted.

"How can we be complacent - we're ranked number four in the world?", he commented.

"We've got a long way to go, and we're only 1-0 up in a five-Test series," he added.

"So that would be a crazy way to think."

The only negative to come out of Adelaide for the tourists was the injury to Stuart Broad which has ruled the seamer out for the rest of the series.

"It's really unlucky," said Flower of the 24-year old's injury.

"He's been an integral part of our side and our relative successes over the last couple of years - but that's the way the cookie crumbles sometimes."

While the absence of the Notts man is a blow to England, Flower is confident that the right preparation was done to accommodate inevitable injuries on tour.

"It's not good for him; it's not good for the side.

"We weren't totally naive in thinking we'd get through the whole Test series without injuries to any of our quicks.

"We thought it was a priority to get some of our back-up quicks into good nick," he said.

Broad's replacement will come out of the trio of Tim Bresnan, Ajmal Shahzad and Chris Tremlett who are all set to feature in England's three-day game against Victoria at the MCB, starting on Friday.

Flower was quick to dismiss the game in Melbourne as a 'bowl-off' between the three seamers, hinting instead that England have already decided on Broad's replacement.

"I wouldn't describe it that way - because you don't judge people on one performance.

"Obviously, we have ideas in mind who would replace Broad. But we will get 270 overs of viewing our potential replacement."

"They (Bresnan, Shahzad and Tremlett) had a good run-out in Hobart; they'll get another one here against the Vics - and you've got to factor these things in," added the England coach.

Eoin Morgan and Steve Davies are the only members of the Touring squad who are yet to feature Down Under and they are set to get a run in Melbourne.

While the tourists are set for just one enforced change for the third Test which takes place in Perth on December 16, the home side have a number of tough selection decisions to make after the embarrassing defeat in Adelaide, with some even suggesting the recall of 41-year old Shane Warne.

Flower, who possesses a healthy sense of humour, is not expecting to see the former Aussie leg-spinner in action at the WACA come next week Friday.

"I've heard about some of the figures he earns - they might need to get some more contributions together there".
