Probably not over the next year, since he has said he feels fit enough to play until he's 50. However, his retirement will be sooner rather than later, as the kind of high-profile clubs he will be wanting to play for, and who actually want him, will become less and less each season as he ages. If he is willing to play at a lower level, such as Edgar Davids now is at Barnet, then he may be able to stretch his career slightly further, probably 2-3 years longer, but one assumes that this will not be the road he takes. It will be more probable that he'll retire just before of after his 40th birthday, and find a way in to coaching/management if football is still in his blood. He may however choose to pursue any number of opportunities, business-wise, that will undoubtedly present themselves to him.
