Manchester United's comeback win at Hull City on Boxing Day has given them hope of producing a title challenge in the second half of the season.
The defending Premier League Champions remain eight points off the top of the table, but will be full of confidence ahead of their trip to Norwich on Saturday. Moyes' side came from two goals down to beat Hull 3-2 in the opening game of a packed festive afternoon of football, and the United manager believes the spirit shown by his side will give them plenty to work with over the remainder of the season.
"To be two down and come back to win is a great result," said Moyes. "I thought it would be a long road back but these players have done this in the past and we did well to get back in the game. For us to get in at half-time 2-2 was great but when we were 3-2 Hull gave us a few scary moments.
"We're going to try to get the gap as narrow as we can. There's a long way to go in the league and we have to keep picking up points. There's a lot to do but we'll keep at it I believe we can be in the mix and challenge whoever is near the top."
Chris Hughton's Norwich were stunned by a late Scott Parker goal in a 2-1 defeat to Fulham on Thursday. The result made it three games without a win for the Canaries, who are now just three points outside of the relegation zone.
Only Fulham have conceded more goals than Norwich's 31. However, 21 of those have come in away matches, with the Canaries allowing just 10 goals in nine games at home. Goals have been scarce at both ends at Carrow Road this season, with Hughton's side managing just 10 themselves.
"We didn't make the most of our opportunities. I am really disappointed not to come away with a result," said Hughton after the defeat to Fulham. "It is a concern when you do not get the result you feel you deserved.
"Lack of goals for Johan Elmander is a concern as you want to be scoring goals throughout the team, but he does give us a work-rate off the front."
Norwich have long-term injury concerns over Anthony Pilkington (hamstring), Elliott Bennett (knee) and Alexander Tettey (ankle). United are without Marouane Fellaini (wrist) and Nani (hamstring), while Rafael and Robin van Persie are doubts.
The three goals scored by United at the KC Stadium on Boxing Day took their tally away from home up to 20 goals. Only league leaders Arsenal can match that figure.
The Canaries beat Manchester United 1-0 in this fixture last season, but have lost all three of the other meetings between the two since their return to the top flight in 2011. United won 4-0 against Norwich at Old Trafford last season, with Shinji Kagawa scoring a hat trick, and United matched that scoreline in a League Cup victory in October, with Javier Hernandez bagging a brace.
