Roberto Martinez has told his side they must get five points from their remaining four games to survive in the Premier League.
Victories over Manchester United and Arsenal in the space of five days has put Wigan five points clear of the drop zone, but the Latics boss knows his players still have work to do.
The DW Stadium outfit face Fulham, Newcastle, Blackburn and Wolves before the end of the season, and Martinez believes they cannot afford any slip-ups.
He said: "In a game where it is three points for a win, five points is nothing.
"When you've got the next four games as difficult as we've got, I'm under no illusions that the fight starts now for us.
"I don't think you're going to need 39 points this season. Last season it wasn't enough, with Blackpool and Birmingham getting relegated with 39.
"I do think it is going to be less than that this time, but that has to be the target.
Until you get those points, you need to be thinking down those lines.
"That's the target to get overall, but if you ask me, the target is to be as good as we can."
