Having suffered a heavy defeat at Huddersfield last weekend, bottom of the table Barnsley desperately need a result against Forest when the two sides meet at Oakwell on Saturday.
Billy Davies has a number of players on the treatment table but his opposite number Wilson told the official Barnsley FC website: "There'll be quality in every position against us."
For Davies, the season now boils down to a 13-game campaign as he attempts to draw a line under recent defeats by Lancashire rivals Burnley and Wigan Athletic.
"We accept it was difficult, but the problems surrounding those games are now in the past," he told Forest Player.
