The 23-year-old England international joined the north-east club on a five-year deal earlier this week following two years at City during which he made just 16 first-team appearances.
Rodwell was considered one of England’s brightest prospects after impressing at boyhood club Everton and the midfielder hopes to recapture his best form.
“I started pre-season with Man City but always thought I should be signing for someone else,” he said.
“It’s been difficult. I struggled with injuries in the first season and didn’t have much playing time in the second.
“It was a great experience and a learning curve but disappointing at the same time. I wanted to play every week there but it didn’t work out like that unfortunately.
“But that’s football, you have to get on with it, and it’s a new chapter now and I’m glad to finally get the deal over the line and crack on.
“I can’t wait to start at Sunderland now. Hopefully I can get the minutes on the pitch and play week-in, week-out.”
@charming man.....haha, so Rodwell is lying about his fitness? Even though he's just past a fitness test....and we're supposed to believe you.....the bloke whose already told one lie on here? You never did explain why you said Rodwell was talking about 'all big clubs', when clearly he wasn't. You didn't 'develop' Hart, he was older than Rooney when he joined United and you then signed the 'finished article' in Given and loaned Hart to Birmingham.....where he actually got his chance. What's worrying is the amount of lies you need to tell yourself in order to be a City fan!- abudelusion
