Manchester United manager David Moyes plans to be active in the January transfer window but only if the right players are available.
United made just one signing in Marouane Fellaini in the summer after failing in bids for Cesc Fabregas, Leighton Baines and Ander Herrera.
Heading into the weekend trip to Tottenham Hotspur, United are seven points behind leaders Arsenal and Moyes is keen to bolster his ranks ahead of a push for the title in the New Year.
"We would like to [bring in some new players], but only if the right players are available - either way there is no guarantee," Moyes said.
After missing the draw with Cardiff City and the win over Bayer Leverkusen, Robin van Persie is expected to return having not featured since the victory over Arsenal with a groin injury.
United travel to a Tottenham side who lost 6-0 to Manchester City last weekend and have only netted nine goals in 12 league games this season.
Having not lost at White Hart Lane in the league since 2001 United travel to north London in good spirits, particularly after the mid-week 5-0 win over Leverkusen which assured qualification for the Champions League knock-out phase.
And after the most impressive win of his tenure Moyes can feel United's form improving.
"I still think the best is to come and I think we can continue to improve and progress," added Moyes.
"We had some little bits of inconsistency at times, which we need to try to do better with, but there have been moments that have shown we are beginning to come right back into form.
"That is what I hope. Midweek [against Bayer Leverkusen] certainly showed what we are capable of when we are playing well and the job is to do that week in, week out.
"They are always good games. We will go there and try to win, as we always do."
After playing 90 minutes in mid-week in Germany, Ryan Giggs is unlikely to play from the start against Spurs as the Welshman celebrates his 40th birthday.
Giggs is yet to start talks regarding a new contract, which expires at the end of the campaign, but Moyes said the veteran midfielder will likely begin considering his future at the end of the season.
"When you get to this stage [in his career], you always make a decision at the end of the season. There will be no quick decision," Giggs said.
"To be playing so well at his age is terrific and he is a great example to the younger players."
