Franco di Santo is determined that Wigan must finish the job despite being on the brink of Premier League survival.
The 23-year-old netted the opener as Wigan beat Arsenal on Monday, just five days after taking three points off champions Manchester United.
The back-to-back wins have lifted the Latics to 34 points - five points clear of the bottom three with just four matches to play.
Victory over Fulham on Saturday could virtually secure an eighth successive campaign of top-flight football at the DW Stadium.
But Di Santo told the Wigan Observer: "We've given ourselves some breathing space at the bottom, but it's not over yet.
"Three wins would be enough, maybe less, but we don't want to let our standards slip now.
"The way we've played in recent weeks, and the teams we've beaten, we're good enough to finish with four wins."
All about points
Di Santo's scored his fifth goal of the season at the Emirates but the Argentine forward insists the points were more valuable than any personal glory.
"It was great to score but it's all about the three points - that's the only thing that matters," he added.
"The last two games have been amazing, but the most important thing is the points we've won and the way the league table looks now.
"We went to Arsenal to win, we knew it would be tough but we had enough confidence generated by the last 10 games to know we can match anyone.
"We believe in what we've been doing, we got off to the perfect start and fortunately we were able to see it through."
