Burnley interim coach Mike Jackson believes Matej Vydra provides a different option in his attack.
The Czech striker scored the winner against Wolves on Saturday.
Speaking to LancsLive, Jackson said: "With Vyds, I watched Burnley play Wolves a year or two ago and he caused them murder so our thinking was 'let him go' because he is a threat and if we can get him proper match fit, because he hasn't played in a while, he is hard to play against.
"Aaron has been carrying a knee injury and the thinking was that we didn't want to lose Aaron and max at the same time.
"We couldn't take that risk but we knew Aaron could get a certain amount of game time and when he came on he did terrific."
