Roy Keane's charges are currently on the bottom of the pile in England's second tier, but 25-year old Rosenior who is on loan from Reading, says by the end of the season that position will have changed dramatically.
"I don't regret my decision to come here one bit," Rosenior said.
"In fact I'm delighted with it. I'm at a better place, I'll improve as a player and this is a bigger club.
"Come the end of the season I'll be proved right because I'm 110 per cent confident that we will end up in the play-offs."
