Swansea City have a golden chance of making history in the semi-final of the Capital One Cup, according to winger Nathan Dyer.
The Swans face a first leg against Chelsea at Stamford Bridge on Wednesday, with Dyer itching for a chance to play in a Wembley cup final.
"For a lot of people this might be their best chance of getting to a major cup final," he said.
"We want to definitely go out there and give 100%."
Swansea have been to Wembley three times before, winning the Autoglass Trophy in 1994 and losing in the Third Division play-off in 1997.
The last time the Swans were at Wembley they beat Reading 4-2 in the 2011 Championship play-off final to become the first Welsh club to claim a place in the Premier League.
Dyer was a key member of that winning Swansea team in 2011, and believes they can scale the heights again.
"Swansea City as a football club and as a city in general has made massive strides from where they were a couple of seasons back to now," said Dyer.
"It's a great achievement and obviously we want to give something back to the loyal fans and to ourselves as well."
"It's Chelsea, they're a very big team, champions of Europe and they've added to their squad with Demba Ba who is a goal scorer.
"So obviously it's a massive squad, but then again we can play football and come away with results ourselves.
"We're a good side, a really good side, and I think a lot of the bigger teams now are thinking we're not a pushover and it is going to be a game."
Swansea have not appeared in the semi-final of one of the two major English cup tournaments since 1964, when they were beaten in the last four of the FA Cup by Preston North End.
