United captain Gary Neville would consider the end of his career "a failure" if he did not win another Premiership title.

The 31-year-old defender, currently on England duty, lifted his first trophy as club skipper in the Carling Cup final at the Millennium Stadium on Sunday.

United haven't won the league since 2003 and, with Chelsea so far ahead in the current title race, would have to wait until at least 2007 to claim the trophy for a ninth time.

"If I stay here for three, four or five more years and United did not win more leagues, I would definitely have to say that the end of my career was a failure," Neville told the club's official magazine, United.

"This club has got to win trophies and I would be seriously disappointed if we weren't to add more league medals to our collections.

"I would feel that I had not quite achieved everything I want to in my career."

United will look to strengthen the midfield in the summer and add a consistency to match Chelsea's proficiency week after week in league football.

Neville is confident that United have the talent to blossom into a successful team.

"We have the talent in the dressing room, as we have shown in spurts this season," he said.

"Where we have won championships in the past is through consistency and we have just not had that.

"You have to be optimistic though when you have got the likes of Cristiano Ronaldo and Wayne Rooney at the club; they are such talented individuals.
