Wigan boss Roberto Martinez believes the performances of fringe players like Callum McManaman are important as results in ensuring their league form receives a boost.
He said: "What's important in those situations is that the competition for places is really strong.
"You do feel you get a real boost internally, you get a couple of players back from injury, you get a very good performance away from home allowing you to progress in the cup and now you can focus on a very, very important league game.
"It's vitally important that we have as many players available to compete for their places from now until the end of the season.
"I think we've been a little bit light in the last few months in terms of numbers and options and then all of a sudden now we're quite strong. I think we'll be stronger for the final third of the season, which is crucial for us."
"Callum is a real example of what we want in our football club - youngsters that, if they work well, if they apply themselves well, are going to have opportunities," added the Latics boss.
"Callum has been doing that. He's been working really hard and enjoying his football, and what he did on Saturday is going to help him a lot but more importantly it's going to help the team because that talent is welcome in any group of players.
"We're delighted that Callum is developing into an impressive young footballer and he's going to be very important for us until the end of the season."
