Jones is expected to start at former club Blackburn Rovers tomorrow night.
"He’s definitely a future captain," stated Sir Alex. "There’s no doubt about that. I said that from the minute he came to us that I thought there was something about the boy."
"He was doing great until he started getting all these injuries and a bit of illness with 'flu.
"That kind of thing has derailed his time with us as he and Chris Smalling have had a nightmare, the two of them.
"If they can stay fit for the rest of the season, it'll be a big bonus for us because they are exceptionally good young players."
