Nahki Wells and his Bradford City teammates will be looking to continue their giant-slaying act against Swansea in tomorrow's Capital One Cup final at Wembley Stadium.The Bantams became the first fourth tier side to reach a English domestic major cup final in 51 years following their 4-3 aggregate win against Aston Villa in the two-legged semi-final.Swansea reached their first ever major cup final after recording a 2-0 aggregate win against European Cup and FA Cup champions Chelsea in the remaining semi-final.City boss Phil Parkinson believes the pressure will be on the Swans to deliver given they are the overwhelming favorites to win. And that, he says, could work to his team's advantage.“Swansea being favorites works in our favour,” he told The Royal Gazette. “We go there as underdogs and have nothing to lose, everything to gain. Our achievement is getting to the final and we'll do our best.“It's a two-horse race but they are massive favourites. We'll go there and enjoy the day, enjoy playing in front of our families and supporters of Bradford City but we'll also remain focused on putting in a good performance.”Even though his team will go into the match favoured to win, Swansea boss Michael Laudrup isn't taking anything for granted against League Two side Bradford who ousted Premier trio Wigan, Arsenal en route to the final.“We have to accept that we are favourites, but I think all my players they know that this is a unique situation for us, but even more for Bradford,” the Dane told BBC Sport. “We're talking history here, and even more so if they win this game. So I'm sure that my players will not underestimate Bradford.”Parkinson will be forced to make at least one change to his lineup from the one that lost 2-1 at relegation-threatened AFC Wimbledon last weekend.Striker Andy Gray is ineligible to play having featured in the earlier rounds of the competition with former club Leeds United.Bantams defender Rory McArdle, who injured his ankle against Fleetwood Town and left the ground on crutches, has returned to training but remains doubtful.Swans boss Laudrup is expected to make a raft of changes to his lineup from the diluted one that suffered a heavy 5-0 loss to Liverpool at Anfield last weekend.Spanish striker Michu, who is the Swan's leading goal scorer with 18 goals in all competitions, is among those expected to return to the fold after recovering from a minor ankle injury.However, the same cannot be said for fellow Spaniard Chico Flores who has been ruled out with ankle ligament damage.Bradford and Swansea have recorded 20 wins each in 54 matches between them with the remaining 14 ending in draws.Both teams last met in 2007 in a League One match at Valley Parade that ended 2-2.
