United travel to Spain ahead of the reverse fixture with Real Sociedad knowing a victory would be a big step towards qualification for the Champions League knockout stages.
"We said about a month ago that we needed to go on a run in the league and pick up some points, and also go on a run in the cup and do well in the Champions League," Jones told ManUtd.com.
"We're slowly starting to get some momentum going and we hope we can carry that on in the Champions League on Tuesday.
"We'll be in a strong position [with a victory] but we need to keep our focus and make sure we go there and get the win."
