The champions got back to winning ways on Tuesday via a 2-0 home win over Cardiff City, however Young moved to quell any suggestion that the players had lost confidence in themselves.
"We always have that belief and there has never been a time when we don't believe," Young told ManUtd.com and PA Sport. "Even when a lot of people have written us off, they are doing it even now, we never have. We always believe - I don't know anybody who is working at the club from the staff to the players that is resting on their laurels."
The England international added that it was his hope that the midweek result against the Welsh outfit would prove the catalyst for an upsurge in form.
"We take each game as it comes and we're hoping to build on Tuesday's performance. We want to get some momentum going into the last part of the season," he added. "After last week [losing to Sunderland in the Capital One Cup] it was important to get back to winning ways. We want to start looking up the league, looking at the teams above us and start climbing back up the table to where we know we can be. Until it is mathematically impossible, we won't count ourselves out."
