The defender, who won 81 caps for the national side over a 14-year period, joined Queens Park Rangers earlier this summer.
The 36-year-old told the Daily Mail: "Everyone has dreams of playing for England and my dream after football is to manage England.
"I don't expect the chance now, but once I get the badges I am there. If I don't get a job in management I will wonder why. I will give myself the best opportunity of getting the job by getting all the badges.
"I don't think people should start shouting the odds about the opportunity to manage clubs until they have their badges. I am not sitting here saying 'give me a job' because I don't have them yet."
