Ireland was snapped up by his former Manchester City manager Mark Hughes on transfer deadline day on a season-long loan deal from Aston Villa.
The 27-year-old produced some excellent form under Hughes and assistant boss Mark Bowen is confident that they can see those sort of performances again.
"There's no doubt he can get his best form back," said Bowen.
"If he was 32, then you might think those days are gone, but at 27 why shouldn't he get them back?
"He should be coming into the prime of his footballing life at his age."
