Roberto Mancini spoke last week of his fears for the former Everton midfielder, who has not played since October, but the 21-year-old is confident he will return to boost the City manager's options by the end of January.
"I feel really fit - I've been doing a lot of strengthening work because I've been out so long with my hamstring injuries so it's taken time," he told the club's website.
"My first injury was my left hamstring which kept me out for five weeks and then my right hamstring started to niggle which put me back to square one.
"It's easily the worst injury set-back of my career because I've been out for more than three months now. It's been frustrating and like most players, I'm not the best spectator in the world - it obviously helps when the lads win - but I'm almost there now."
Rodwell has made just six appearances since his summer move from Everton and he is keen to show City fans what he can do.
"I feel like my career here hasn't really got started yet, even though I feel really settled and at home now.
"I'll begin full training this week - all being well. Then I'll need 10 days to a fortnight to get back up to speed and I'll be available for selection again."
