United already trail early leaders Chelsea by seven points after following up an opening day defeat at home by Swansea City with draws away to Sunderland and promoted Burnley.
New manager Louis van Gaal has implemented a 3-5-2 formation since taking charge, which has seen Young operating in a left wing-back role.
Young believes it will take time for the system, and several new signings, to gel and he is not unduly worried by United's sluggish start to the campaign, which has also included a 4-0 humiliation at the hands of MK Dons in the Capital One Cup.
"In previous seasons when we haven't started the season so well we've gone on to win the league," Young told Inside United.
"People have written us off already but everyone here knows you don't write off a club like United.
"People can say what they want but internally we all know exactly what we're striving to do, what goals we've set and what we want to achieve.
"There is no point panicking after a handful of games. It's obviously been disappointing but you have to take the positives from the games we've had.
"I definitely think things are going to turn for us and I would say to the fans there is nothing to worry about, we're going to come good.
"It's just like the manager has said: just believe in the philosophy and how we're playing and keep believing that we're going to turn this round - because we do.
"The manager has said things aren't going to change in a week or a month. It's going to take time for the players to adjust.
"We want to get results and I'm sure given the way we've worked in training the right results will come.
"We've got to keep thinking in the way that he has explained it to us and keep performing in the way he wants.
"Obviously things haven't gone the way we've wanted them to yet but we've just got to keep working on that philosophy that the manager wants, keep doing what we've been doing in training and show the spirit and togetherness that we always show.
"If we keep doing that then I'm sure everything will gel together and come good."
