At the moment, Jones is playing every other game because Smalling and Rojo have been injured and Bailly is in poor form.
United will (hopefully) sign a top class defender in the summer, Tuanzebe will likely get a Premier League loan and Rojo and Darmian will leave.
Like him or not, the club needs Jones next season. He's a loyal club man who seems well liked around the club and doesn't seem the type to cause any dressing room disharmony.
I also hate the idea of player contracts running down, especially in this era where every EPL club is minted. If by next January or the end of next season he hasn't played a single minute, Burnley can sign him for £15m.
