And that could open the door to a bid from Newcastle United.
The 35-year-old former England captain has been in and out of the side in a season of transition at Old Trafford, with his contract set to expire in the summer.
Indeed Ferdinand did not make the match-day squad for the final home game against Hull this week as interim manager Ryan Giggs gave a glimpse into the future.
Nemanja Vidic is leaving the club this summer, and it remains to be seen what United will do with Ferdinand.
Two weeks ago it was reported he could be heading to QPR, but that depends if they win promotion, and Newcastle could be a better option.
Mike Williamson has had his critics of late, and no-one could argue Ferdinand is more vocal and would organise the back-line better.
Ferdinand - who joined United from Leeds in July 2002 for a then record £30million - feels he still has plenty to offer.
Rio Ferdinand: "I am fit, I am healthy and I want to continue playing.
"I have spoken to a lot of mates of mine in the game and they all say the same thing - keep playing for as long as you can.
"The club at the moment is in a position where they can't really make any decisions about anything.
"For me to be saying I want to do this or that is irrelevant, because we have got to see who becomes the new manager and boxes will be ticked from there.
"I just want the best solution for the club. Whatever it is, then I will respect it. After that I am open to offers.
"But I would rather wait and see what happens at United and then there will be a decision to be made.
"Obviously I want to stay in the Premier League and I feel I can still do a good job in that league.
"I will look at what is on the table when the season finishes."
