The Swans take on the League Two Bantams at Wembley on Sunday and Spanish full-back Rangel has made it clear that the Premier League outfit will not be taking their opponents for granted.
"People can talk about this game being a League Two club taking on a team from the Barclays Premier League - but I don't think it matters who we are playing," he told the club's official website.
"That's because it's a final and both teams are going out to win. As Bradford have shown, they have the quality to beat Premier League teams, but we have also shown our true qualities in this competition.
"But if you look back to where our run started, it shows you that we had to beat a Championship team in Barnsley before going to Crawley.
"We had to really battle at Crawley - they are a tough League One side. But we showed the other side of our qualities as a team.
"We like to pass the ball around with a lot of movement and that will hopefully be what we will do on the big pitch at Wembley, but we can also dig deep. That is a key quality.
"But it all depends on the day, of course, and we are all really looking forward to returning to Wembley and playing our part of what is a massive occasion for both clubs."
