The midfielder joined the Potters on a season-long loan from Aston Villa on transfer deadline day last week.
The move reunited the 27-year-old with manager Mark Hughes, his former boss at the Etihad Stadium.
Ireland has not played in the Barclays Premier League since January but he has no doubt he is ready for action as City visit the Britannia Stadium on Saturday.
Ireland told #pottersmag: "I'm fit and raring to go.
"I don't want to be eased in and I don't want to have to take my time; I just want to get straight in there as fast as I can.
"I want to participate in whatever way I can, whether that be for the full 90 minutes or whether it be coming off the bench for the final five minutes.
"Whatever time I get I will give it everything I have. It's been a long time in the waiting for me so I want to get going and show everyone what I am capable of."
Ireland is pleased to being working under Hughes again having enjoyed the best spell of his career under the Welshman.
Ireland came through the City youth ranks and shone after bursting into the first team in 2005, but left for Villa five years later after falling out of favour under Hughes' successor Roberto Mancini.
Ireland said: "We had a great relationship when I was at City and I'm delighted to have the opportunity to work again with him and his staff, Mark Bowen and Eddie Niedzwiecki, because they did so much for my career first time around.
"They are the best coaching staff that I have ever had, and I always tell people that.
"They inspire me, they make me feel good and I am finding myself smiling again now, which hasn't been the case for a long time."
