ALAN Curtis believes winning the Capital One Cup will be Swansea City's greatest achievement.
Curtis, now the club's first-team coach, has played a key role in most of Swansea's greatest moments.
He played in the team which won promotion to Division One in 1981 and was a member of the squad which finished sixth in the First Division a season later.
He was also part of the coaching team when Swansea clinched promotion to the Premier League two years ago.
But he believes all that will be eclipsed if Swansea can beat Bradford in the League Cup final at Wembley on February 24.
"These guys will go down as legends of this club," he said.
"If we can win the final it will be the biggest achievement in the club's 100-year history.
"Getting into the First Division years ago and winning promotion to the Premier League was phenomenal.
"But if you can win a major trophy at Wembley, then that would top it.
"It is beyond our wildest dreams."
Swansea reached the final thanks to a 2-0 aggregate defeat of Chelsea in the semi-final.
It will be Swansea's fourth trip to Wembley.
They won the Autoglass Trophy when beating Huddersfield on penalties in 1994, but lost to Northampton in a play-off final three years later.
Their latest visit saw them beat Reading 4-2 to seal promotion to the top flight.
Curtis added: "In all my time at the club, there have probably been more lows than highs.
"But I must say when the highs have come along they have been incredible highs.
"So it's a fantastic achievement for us to reach a major cup final.
"It's building up to a fantastic day at Wembley."
