The Reds are currently experiencing their worst league season since 1989/90 - when they still ended up winning the FA Cup - and Moyes wants his squad to focus on 'putting things right' between now and May.
Moyes recently smashed the club's transfer record to purchase playmaker Juan Mata from Chelsea and, speaking in his programme notes ahead of Tuesday's Premier League match at home to Cardiff, he said: "I do believe now that we are playing for the Manchester United jersey and for pride in where we are.
"There is still a long way to go this season and by the end of it we have to have shown we are much better than many people are making us out to be.
"On the training ground and in the dressing room I see determined and committed players who are desperate to put things right.
"When I joined the club, I joined knowing I was taking over a great squad who had just finished the season as champions but I was also made very much aware that there would have to be changes made.
"Namely a long-term plan and also looking within our own academy to introduce young players to the first team as often as we feel they warrant selection."
