Victorious Wigan boss Roberto Martinez has urged his players to maintain their focus after claiming a historic win against leaders Manchester United.
The Latics climbed out of the Premier League bottom three courtesy of Shaun Maloney's second-half strike.
Wigan, who had lost all 14 previous meetings with United, have five games left to guarantee their survival.
"It would be foolish to think we are out of the bottom three and we will stay there," said Martinez.
Martinez also dismissed rumours circulating before the game that he was planning to leave the club in the summer.
"I heard that and was very surprised," he said. "You wonder where that rumour is coming from. At this stage of the season there is a real fight amongst the bottom five, you feel stories can upset clubs internally.
"There is nothing true about it. I signed a new deal in the summer for an extra two years. That was my conversation with the chairman and nothing has changed since."
Wigan, who climbed above north-west rivals Bolton and Blackburn with a priceless victory at the DW Stadium, know exactly what it takes to avoid the drop after clinching top-flight survival on the final day of last season.
And Martinez predicted another nail-biting finish after beating United.
"When it counts is 13 May," said the Spaniard.
"We've got five games left, it will be a tight fight and we can't do anything apart from enjoy today and then prepare for the next game.
"The most pleasing aspect is that the win was nothing lucky.
"In our history we've never taken a point from United and we restricted them to one shot on target.
"I saw a team working hard, keeping the ball well and taking a deserved lead. Then we defended well and tonight we get the credit we deserve.
"We've been playing well. Sometimes it's too easy to just look at the scorelines but we've played well recently and it's a historic moment. We should be proud of these players. United are the team in form so to match them takes a lot."
Wigan's impressive display has stalled United's charge towards retaining their title and manager Sir Alex Ferguson backed the Latics to survive.
"You have to recognise that Wigan are in a false position," he said. "They play some of the best football in the league you have to credit them for that."
