Jordi Gomez claims Wigan will welcome Liverpool to the DW Stadium on Wednesday confident in their ability to pull off another shock result.
The Latics impressed many observers on Saturday evening as they stunned Chelsea with a dramatic late show on home soil.
Gomez's goal two minutes from the end of that contest saw Wigan take what could be a priceless point from the title-chasing Blues.
Things do not get any easier for Roberto Martinez's side, with top-four hopefuls Liverpool providing another sizeable test in midweek.
Wigan will enter that game inside the Premier League drop zone, but Gomez says recent performances have given everyone connected with the club cause for optimism.
"In the last three or four games, the team has played very well and with confidence, and that allows all the players to show their best form which brings about the results we've been having," the Spanish midfielder told the Wigan Evening Post.
"This result means we go into Wednesday's game against Liverpool with belief, and we don't care who the opposition is when we play like we know we can.
"No-one can deny we deserved at least a point against Chelsea, and the challenge now is to pick up at least the same result on Wednesday night.
"Yes, it is a hard run over Christmas, but you just have to take it game by game and try to do your best in each game.
"We are not thinking about the games we are playing next week or next month - all we are focused on now is Liverpool and we will be trying our best to get another good result."
