The former Everton midfielder has recently made his comeback from injury and, after scoring twice against Norwich, cannot wait for the new season to start.
Roberto Mancini was sacked after losing the Premier League title to Manchester United by 11 points and falling to defeat against Wigan in the FA Cup final, along with the team's group stage exit in the Champions League.
Manuel Pellegrini is the heavy favorite to replace the Italian at the Etihad Stadium, and Rodwell says the players will be trying their hardest to make a good impression on the new manager, whoever that may be.
"It's all about the future now," Rodwell told the Daily Mirror. "A new manager will come in and everyone is intrigued to see who that is going to be. It's a fresh start for everyone and we will all be 'on it'. The first game of next season everyone will be flying and we'll do our best to prove ourselves to the manager. We just have to get on with our jobs.
"We're on our way to New York [for a post-season tour], we have a couple of games over there against Chelsea, then we will all have a good holiday and a couple of international games. [In many way] the season has just started for me. I've been back playing for the last few weeks and I just want more. We've got this last stint in New York, then I'll have a good summer, so it's a good time to relax."
Rodwell has been called up to the England squad, with Tom Cleverley set to miss out through injury troubles, after the final game of the season saw him score twice in City's 3-2 home defeat to Norwich.
"It's been a frustrating season, but on a personal note it was a good game for me," the midfielder said. "We could have done with a different result, but I'm happy. Once I'm fit, I can do what I did for that second goal - and I can do it for 90 minutes. It's just getting games under my belt, getting match fitness. And hopefully next season I can do it a bit more.
"I'm a great believer in my ability, but I've not had the chance to prove it. I'm back for one game after 10 games out and it's always hard. You're never match fit and it's hard to produce. You need a good run of games to do that. I've ended the season on a good note personally, now I can put my mind to rest and have a fresh start."
