A brace from Berbatov and one from Hernandez rescued secured United's comeback and denied Blackpool a famous win.
Berbatov said after the game: "Yes because we're always confident that if we can score one we can score more and that was the case today.
"We fight like a team. In the second half we showed spirit and we won.
He added: "You come here, it's not a friendly ground. The pitch is not as ours back home at Old Trafford.
"Blackpool played a very good game and scored goals, they could easily have scored more in the first half.
"In the end it was the team spirit that won the game."
United boss Sir Alex Ferguson was delighted with his side's fighting spirit after a "terrible" first-half display.
"They just never give in," he said. "In the first half we were battered. We couldn't handle Charlie Adam. We were terrible.
"I don't know the reason for the first half. We were all over the place. Maybe we were too confident.
"We changed at half-time, Ryan Giggs made a tremendous difference. We started to penetrate and I think we were deserved winners in the end."
"I know the game's never done in situations like today," he said. "You know at some point we're going to do something.
"You'll get games like tonight. Maybe sometimes we won't come back but we'll always try to come back."
Of Hernandez, he said: "His pace and timing of the runs is fantastic. He's so good at that. He could have scored four goals. He's made a tremendous impact."
And of Berbatov he added: "He's having a great season. He has great talent. The third goal, the composure, I was screaming for him to square it to Chicharito but, no, he has the confidence and ability to do what he did."
