Wigan boss Roberto Martinez claims his team must be a "nightmare for pundits" after completing another remarkable escape from relegation.
Widely written off two months ago as they languished bottom with 20 points from 27 games, Wigan have produced a dramatic escape by doubling their tally to stay up with a match to spare.
Monday night's 1-0 victory at Blackburn completed their turnaround, and Martinez said: "I always had the belief because I know the players and we did it last season. We have a young group with real energy, the youth and bravery allowed us to finish really strongly, but more than anything it is the characters in the club."
He added: "We have got 12 or 13 different nationalities in that dressing room but they have got a real responsibility. They want to represent Wigan in the right manner and their standards on a daily basis are what you have seen on the pitch.
"To get the results we have of late and achieve something not many people predicted we would in December, I think we are a nightmare for pundits in world football."
Key to Wigan's upturn in fortunes was Martinez's bold decision to switch to a 3-4-3 formation and play with three centre-backs and wing-backs.
The result was a reinvigorated approach which in the last eight games has yielded six victories, including against the likes of Manchester United, Arsenal, Newcastle and Liverpool.
Martinez said: "We had to do it because whatever we were doing wasn't working.
"But it is not about systems it is about the way the players can be at their best.
"The way we are playing now probably gets the best from our players. It gives us a real good balance."
