The Mexican marksman headed the equaliser at Stamford Bridge last weekend - just as he did at Anfield last October - and this precious point means the Reds can go top, at least for one night, by winning the home game against the Merseysiders.
"We went home [from Chelsea] with a lot of confidence," revealed Hernandez. "To come back from 3-0 down shows the spirit of our team. Throughout Manchester United’s history, the team has never given up. We fight until the last minute.
"Right now, Manchester City are two points ahead of us but there are a lot of games to go, so we need to look forward, keep working and keep fighting."
Hernandez has already faced Liverpool four times in his first 18 months as a United player, with each clash bolstering his knowledge of English football's biggest duel.
"I have learned about the rivalry between Manchester United and Liverpool," he said on Friday. "But I knew a lot about this already in Mexico. In all the world, people know about the history of both teams, with so many Premier League titles and European Cups between them. It is a very important rivalry.
"[The build-up to this game] is a bit different. We work just the same as we have done for every game. But in the back of your mind, you know it is Liverpool."
