The England prospect hasn't looked back since his controversial move from Blackburn Rovers.
Jones told the Sunday Telegraph: "It was brilliant when I heard of United's interest, an incredible feeling.
"The whole experience - speaking to the manager on the phone, meeting him in person, going through the whole process of signing - was fantastic.
"Lots of clubs showed an interest in me, but United just felt right; the whole club, the set-up. It wasn't the fact that it was United, it was that I walked in here and met people, the staff and physios et cetera, and it just felt right.
"At Blackburn, when I knew there was interest from bigger clubs, I said to myself that if it [a move] happens, then it has to feel right and this felt right."
