Carney and fellow United new signing James Beattie paraded the ground before the match against Nottingham Forest.

New boss Bryan Robson revealed: "David is a young, exciting wide man who has just pushed his way into Australia's national team.

"He has good ability and we can encourage that. I regard him as an attacking wide player."

Carney had been estimated to be worth as much as $1 million - but the final transfer fee was settled for a mere $125,000.

The former Sydney hero has now signed a three year deal with the club which has been reported to earn him around $1.25 million a year.

Carney revealed he took advice from Mark Schwarzer and Mark Viduka before inking the Blades contract.

"It's good to finally be here," he told the club's website. "I'm looking forward to working with Bryan Robson.

"I had offers from a couple of European clubs, and I did think about it a lot but, having spoken to Mark Schwarzer and Mark Viduka about Bryan, that sealed the deal.

"I enjoyed my time in Sydney, and had a good couple of years there. I started to get coverage from the Australian press which saw me called up to the national team."

He added: "I'm a positive, attacking player who likes to get at players, get crosses in to the box and score a few goals."

"I've just played in the Asia Cup for Australia in Singapore and Thailand doing double sessions in roasting heat.

"I'm a bit jet-lagged at the moment, but I'll be fine and raring to go for the start of the season."

Midfielder Lee Hendrie made his debut but it was United striker Billy Sharp who scored on his return to Bramall Lane to hand the Blades a 1-0 friendly win.

The 21-year-old learnt his trade in the United academy but was unable to break into the first team under Neil Warnock, who allowed him to leave for Scunthorpe in 2005.

Robson re-signed him for the Coca-Cola Championship club this summer and it took just nine minutes for Sharp to make it a happy homecoming when he was on hand to hook home from close range after a defensive lapse.

Sharp's former team-mates at Scunthorpe had to settle for a 1-1 draw in their Lincolnshire derby with Grimsby at Blundell Park as Andy Crosby opened the scoring for the Iron before having to leave the pitch.

And it was his replacement Andy Butler who scored an own goal to level for the League Two side.

Southampton recorded a 1-0 win at Brentford thanks to Marek Saganowski's finish from Nathan Dyer's cross just after the interval.

Championship new boys Bristol City had to settle for a 2-2 draw with Bournemouth at Ashton Gate after twice falling behind. Brian Wilson and Louis Carey were the men to find the net for Gary Johnson's side.

Barnsley completed their pre-season programme with a shock 2-0 defeat to Bury at Gigg Lane courtesy of goals from Richie Baker and Dave Challinor.

Blackpool, also looking forward to their Championship debut next weekend, crashed 2-1 at Carlisle.

David Fox gave the Seasiders the lead with a fabulous volley, but United hit back after the interval and goals from Chris Lumsdon and Danny Graham were enough to claim the win.

Hull rounded off pre-season with a goalless draw against Belgian club Antwerp at KC Stadium.

Dagenham warmed up for their Football League bow next weekend with a 2-1 win over Fisher Athletic, Paul Benson and Jon Nurse finding the net.

Robbie Fowler made his first appearance for Cardiff in their 1-0 win over Dutch opponents Twente at Ninian Park.

The former Liverpool striker's debut lasted just 24 minutes, however, as he struggled to shake off the effects of a thigh injury suffered in training earlier this week.

Warren Feeney scored the only goal, smashing home from Trevor Sinclair's free-kick.
