The Mexican livewire was handed the responsibility of penalty duties for the first time during Tuesday's encounter with Stoke City after regular taker Wayne Rooney was ruled out through injury.
With Rooney keeping a watching brief on the sidelines at Old Trafford, Hernandez calmly sent Stoke custodian Thomas Sorensen the wrong way to open United's account in the 38th minute.
"There are a lot of players here who can take penalties here," Hernandez told MUTV.
"Sometimes it's Wazza, sometimes it's Ryan Giggs. Today it was me and Berbatov."
"I take them for Mexico and I'll be ready if [United] ask me again. If they want me to shoot one, I'll shoot."
Hernandez has now notched an incredible four goals in four matches against Tony Pulis' men, although the nippy frontman insisted that his record against the Potters was simply a ""coincidence"
"I just try to do my best and help my team with goals," he shrugged. "I always say, the most important thing is the points. It doesn't matter who scores.
"Against Stoke we did a great job against a very difficult team. It was a great night for Manchester United, with City dropping points and us winning against a very difficult team."
"Will it be very significant [in the title race]? Maybe not, but it was a very good night for Manchester United fans."
United manager Ferguson also lavished praise on his sharpshooter in his post-match interview following his side's 2-0 victory against Stoke.
"I thought Javier did very well," the boss told MUTV.
"His form's come back. Over the last few weeks he's been very good in training. It's just a matter of getting the opportunities because Danny Welbeck has been playing so well."
United are now level on 54 points with arch rivals Manchester City following the Citizens' shock 1-0 slump to Everton.
