Despite establishing himself in the first team last season, Hernandez has found it hard to maintain a place in the starting eleven due to an unfortunate spell of injuries and the emergence of Danny Welbeck.
However, he has still managed to score 12 goals in 19 appearances, and the young Mexican striker will be hoping to contribute more to his side in the title run-in.
Hernandez told ESPN: "It's a part of the season that all the players want to be involved in.
"It's a long season so these final few games are more emotional for everyone, but we have a big chance to win the Premier League again.
"We're in a great position because it depends on us - if we win all our games, we'll win the league. We're not in Europe, so we'll probably be a little bit fitter because we're only playing each weekend and have long weeks to rest and prepare for each game."
The 23-year-old also spoke of adapting to life in the physical Premier League.
He said: "I want to be a world-class player, so I need to work on every aspect of my game: my movement, goals and body strength, because I'm not the tallest or the strongest."
"I need to be ready to compete in this tough league because it's very physical, quick and technical. With the help of the coaches and my team-mates, I'm improving day by day.
"I do my best and if the manager wants me to play one minute or 90 minutes, I need to be ready to help the team."
Manchester United will next face Blackburn at Old Trafford on Monday in their title defence.
