Roberto Martinez's side take on United at Old Trafford on Boxing Day with history pointing to another three points for the reigning league champions. But Caldwell claims draws against Chelsea and Liverpool have inspired Wigan to believe they can finally upset the odds. He said: "To do something this club has never done before and get a result from Old Trafford would be very special. "We're going there ready to give everything we've got, full of confidence and with a belief that we can do something. "Of course, they're a top team, have home advantage and are right in the thick of a title challenge, so it'll be very difficult but an excellent opportunity to continue the strong run we're on. "To lead the out into the best stadium in the league will be a special moment; as a kid growing up I remember watching the likes of Eric Cantona and Ryan Giggs playing there and taking opponents by storm. "So it'll be a big day for everyone concerned and we all believe we can get something from the game and make it a special day for the fans." Wigan are on a roll of only one defeat in their last six matches and although they are still third-from-bottom Martinez says he is not even entertaining the possibility of relegation. Martinez said: "It's a big mistake to start talking about relegation in December. "We are ready to face adversity and be as good as we can. "I always say that for me there is no bottom three. The way the competition has been going it's a bottom 13. "There are two clear groups - the top seven are reaching a very strong level and are competing for the Champions League and the title. "The other group you have 13 teams fighting to see who says in the league and who will go down."
