United currently occupy first place in the Premier League following the first round of fixtures and Lingard says that Jose Mourinho's side are feeling confident at the moment.
The 24-year-old told 'Sky Sports News': "There's a lot of confidence flying around at the moment and it's good that we can stick together and be a part of it.
"Even the lads who weren't involved at the weekend still played a big part in the win.
"We've come off the back of three trophies, so the confidence is flowing.
"The group that we had it was easy for players to settle in, the likes of Rom [Lukaku] and Victor [Lindelof], it was always going to be easy for them. They're very down to earth guys and they want to work hard on the training pitch."
When asked if United could win the Premier League this season the England international was in a positive mood.
"I don't see why not," he replied. "The whole team is working hard this season and hopefully we'll win trophies. We're in a lot of competitions, the more trophies the better."
Is Lingard right? Can United win the Premier League title this season?
