Captain Gary Caldwell believes Wigan are starting to generate some momentum after a second win in three matches, but insists it is lessons learned in defeat which will be important in the coming weeks.
Having taken no points from eight games between September and November, Roberto Martinez's side have picked up seven from the last four, with their latest victory coming at West Brom on Saturday.
As the Latics prepare to face Chelsea, Liverpool and Manchester United in successive fixtures, Caldwell said: "It was a massive result (at West Brom). We knew that going into the game because the fixtures after it are against the big teams in the league. We knew we needed a win to give us confidence and momentum going into those games."
The Scotland international added: "I think we hung on when we were under pressure and dug in as a team and it shows great character that we can do that.
"It is now about taking it on because we were disappointed by our performance against a top side (Arsenal) and hopefully we can learn from that against Chelsea, Liverpool and Manchester United."
Caldwell also praised 20-year-old Victor Moses, who scored his first goal for Wigan since November last year.
"Vic has been having an excellent season without that final bit to his game," he told Latics Player.
"But hopefully that goal will give him the confidence to go on because he is a great talent."
