Boss Roberto Martinez insists Wigan are in a better position after the transfer window despite only bringing in Jean Beausejour.
The Latics, who are five points adrift of safety and sit rock bottom of the league, were linked with a number of names on deadline day, including Andrew Johnson and Adrian Mariappa, but did not make any further signings.
Chairman Dave Whelan was quoted as saying Fulham striker Johnson did not want to move up north but Martinez was keen to put the matter to bed and look ahead to their remaining 15 games.
"The real situation is we finished the window with a stronger squad than the one we had at the beginning and that's always the work we're going to put in," he said.
"We welcomed an outstanding footballer, a great international with incredible experience, Jean Beausejour, and I think he showed straight away the impact he had with the squad, so we're delighted with that.
"We work hard as a football club, we lost nobody and we added, so it's been a positive period for us. We're in February now and it's time to move on.
"We've got an exciting month in front of us, it's a time where we know as a football club we have to find a way to be consistent and win games on a regular basis.
"Whatever happened in January, whatever happened early on in the season, it will count for very little from now on. We are together, it's been a difficult period, nobody enjoys not getting points on a regular basis but we've found a way to be competitive in every game.
"Now it's a matter of affecting the scorelines and making sure we start a very strong run, especially in the eight games that we've got left here at the DW Stadium, and that's what we're going to focus on."
