Hernandez, who scored the winner on 80 minutes, hopes his side can continue with a run of wins, starting with the League Cup clash against Norwich City on Tuesday.
"I enjoyed it a lot because I helped the team and we got the three points because now we have won two games at home and that was the main goal that we had," the Mexican striker told MUTV.
"We have another game against Norwich here at Old Trafford, we want to get through in the Capital One Cup and keep winning.
"We want to win and win and win. Hopefully, we can do that."
United return to Premier league action next Saturday when they face Fulham.
