McArthur, whose side make the trip to Fulham this afternoon, admits that the Latics are full of confidence ahead of the final four games of the season. However, he insists that there is still much work ahead.
"The job's not done," he told the club's official website. "What the recent results have done though is give us something to build on.
"We go to Fulham next and we'll go there aiming to win the game to see how much further we can kick up the league. We're raring to go again.
"We have to keep this momentum going and make sure we get the results we need from these final games, starting at Craven Cottage."
Wigan are five points clear of the relegation places.
