Jones, 29, has been back training with United in pre-season but looks unlikely to ever regain a regular spot in the senior side after a horrid injury battle.
His hopes of a shock comeback have further diminished following the summer arrival of Raphael Varane with Victor Lindelof and Eric Bailly also battling for a back-up spot in the squad.
Jones hasn’t played for United since January 2020 and was oddly handed a new four-year deal at the club back in 2019, the same year fellow defender Chris Smalling left for Roma.
Ferdinand admits he is baffled by the current dynamic at United and he believes a fresh start for Jones would be of interest to all parties involved.
“He’s taking up a youth team player’s position in that squad right now,” Ferdinand told Vibe with FIVE.
“He’s had too many injuries… I was in the same team as Phil Jones, he came from Blackburn as a young kid, everyone was saying he was going to be this great player.
“Huge potential but injuries have absolutely annihilated his career and then confidence issues at certain times as well.
“He’s never been able to fully establish himself in the team. Whether it’s injuries, lack of form, lack of confidence.
“I think he should’ve gone ages ago. He should’ve gone before Chris Smalling went. Find a new club and play some football.
“He’s lacked consistency throughout his career at Man United. That’s a fact, for all the reasons I stated before.
“I am baffled at how he’s still been given a new deal at the club given his past few years at the club. It just doesn’t make sense to me how you get a new deal.
“I remember back in the day you’d have to do some absolute graft to get a new deal. You’d have to be putting in performances, you’d have to be a vital member of the team. Phil Jones isn’t that.
“He’s done well. Listen, good luck to him if you can get it. Staying at Man United is a great gig, but I look at him as a person, are you really going to be happy sitting there all these years?
“To be fair to Phil Jones, I’ve not seen him come out and speak and clarify, he might have had injuries we don’t know about. But if he’s been fit and has been sitting there like he has been, sign a new deal and stay and not go out on loan… that’s not what a footballer wants to do.
“If I was in the squad with someone like that I wouldn’t talk to them. They are a waste of time, why would I chat to you and give you any energy, taking that away from my other teammates who are here to play and go into battle for 90 minutes every week.”
