Asked if Saturday's match at their top-four rivals is now a must-win game, Lingard told MUTV: “Yeah, it's another free hit.
“We'll go there with the mindset of winning, staying on the front foot, being intense, doing the basics and having that energy to go and win the game.
“We need to work hard first before you can start playing, so win the individual battles and then we'll win the game hopefully."
Lingard, who came on as an early substitute for injured Paul Pogba, added: “Every time I put a United shirt on, I want to give 110 per cent, bring that energy to the team, the pressing.
“Obviously Liverpool are a good team but I think second half we started a little bit brighter, we were on the front foot a bit more and it just gives us that little bit more intensity.
“But we can't be getting beat 4-0. It's embarrassing, really."
