Shaun Maloney admits Wigan have exceeded expectations over recent weeks to give themselves 'a right good chance of staying up'.
Few gave the Latics much hope of beating the drop when they were languishing at the foot of the Premier League table and facing up to a daunting run of fixtures.
They have, however, taken five wins from a run of games that has seen them stun Liverpool, Manchester United, Arsenal and Newcastle.
Roberto Martinez's side have suffered only three defeats in their last 12 top-flight fixtures and are now three points clear of the relegation zone.
It has been a remarkable turnaround at the DW Stadium and Scotland international winger Maloney has called on his Wigan team-mates to ensure that all of their hard work does not go to waste.
He said: "A couple of months ago a lot of people were writing us off. We knew we had it all to do, particularly with the fixtures we had.
"Could we have believed it? If you'd looked at it at the start of that run, no, probably not.
"But when we looked at individual games, like going to Liverpool, we did believe we could beat them.
"It kind of snowballed from that.
"To beat Manchester United at home and then go to Arsenal, those are games from which we probably didn't expect to pick up six points. That has been a massive bonus.
"We've a right good chance of staying up. We must not waste it."
