England captain Eoin Morgan lamented losing a cluster of early wickets as they went down by three wickets to Australia.
Eoin Morgan rued England's dismal start after they fell to a three-wicket defeat in the opening tri-series encounter with Australia on Friday.
Mitchell Starc pinned both Ian Bell and James Taylor lbw in the first over, as the visitors fell to 0-2 after three balls at the Sydney Cricket Ground.
Morgan's 121 did lift England to 234 all out, but David Warner's domineering 127 paved the way for Australia to reach their target within 40 overs and secure a winning bonus point, which could prove important in a series also involving reigning world champions India.
"We did well to get to 234 after the early wickets, but 250 would have been better," Morgan said.
"Ultimately the early wickets cost us. Starc swings the ball like Jimmy Anderson, so credit to him. We still won't know what a par score is if we look back, losing wickets throughout the innings cost us.
"Overall really disappointed, simply because we came into the game with a lot of good preparation under our belt and within the side we would have had a lot of expectation on ourselves, so we have a lot of disappointed guys in the changing room.
"But we're going to have to dust ourselves off and come back in four days [against India]. There are certain positives we can take from the game but ultimately being four wickets down so early has cost us."
Morgan also suggested that premier strike bowler James Anderson will return to face India in Brisbane as he recovers from an unspecified injury.
"Jimmy's likely to play next week," he said. "Obviously with four days [until the next game] it'll be three days of training before then so providing he improves throughout the week he'll be more than likely for selection.
"I'm not 100 per cent sure on his injury to be honest but he is crucial to our bowling line-up. He's our most experienced player, he's highly likely to take wickets early because of the amount of swing he gets and he's great to have in the team."
Morgan's opposite number George Bailey, meanwhile, hailed the performance of man of the match Starc, who finished with 4-42 from 8.5 overs.
"Outstanding, and especially the start Starc gave us," he said.
"He's coming down at really good pace and he can rip through the heart of a team.
"[Pat] Cummins is coming along nicely as well and [Mitchell] Johnson will be back with [Josh] Hazlewood so we have some good pace."
