Sunderland defender Kilgallon impressed by Wolves and McCarthy
"They struggled at the start but seemed to get really organised and became a hard team to beat," he told SAFC TV.
"It'll be a hard game, plus it's away, but we want to go there and try to finish the season well. They won the Championship easily last year; everyone knew they'd have a good chance of staying up.
"They've done it with a few games left and I don't think they've been in the bottom three too much.
"That shows Mick McCarthy's got them playing well and playing for him.
"Molineux is a hard place to go. Their fans get behind them, it's a big pitch and a nice ground so I'll enjoy the experience."
