United's lead at the top of the table was cut to five points when they conceded an injury-time equaliser at White Hart Lane.
Since drawing with Swansea on 23 December, United have taken maximum points from their four matches prior to Sunday's slip.
Jones said: "Confidence is high but we know we still have to produce and do our job every time we step out on the pitch.
"As long as we're focused on what we've got to do and on our game-plan hopefully we'll be okay.
"The Christmas period is always tough with a lot of games in a short space of time, but now we're getting towards the nitty-gritty part of the season.
"It's the time when you need to be fully aware of what you've got to do and go out and do it.
"We all relish the challenge - everyone in the squad is very focused and committed and we're all ready for the next game."
