"The treble is too far in the distance," Jones told The Guardian. "We just have to concentrate on the games coming up.
"We have a good team here and a solid foundation. This year we are more concentrated on us and what we are about. You can see it with all the lads in training.
"We have lots of games coming up. There are a lot of tricky games and it is a tough period but we know if we have everyone fit, we will be fine."
United's next game is against Southampton on Wednesday.
