Manager Roberto Martinez has challenged a number of his fringe players to earn themselves a role in Wigan's relegation battle with a good FA Cup performance on Wednesday.
Bolton visit the DW Stadium for a fourth-round replay and, as in previous matches in the cup, Martinez plans to make a number of changes from the team which earned a creditable draw at Liverpool on Saturday.
But the Spaniard has told those who feature against Wanderers to view it as their opportunity to prove they can help out in the club's battle to avoid relegation from the Barclays Premier League.
"I see it as a great opportunity to increase the squad of players we are going to have available until the end of the season," he said.
"Places are up for grabs because the position we are in the table does not guarantee anyone a place in the starting line-up
"It is quite clear who needs to have the chance to play and every game is an opportunity for any player to show what they can do and how much they want to be involved until the end of the season."
