The 23-year-old says he doesn't see the value in shutting up shop at 1-0, preferring to go all out to win games with an intense, attacking style.
Liverpool's 5-1 win against Arsenal in February acts as the perfect evidence, with Welshman Allen citing it as an example to follow in all of the Reds' future fixtures.
Brendan Rodgers' side are seven points behind Premier League leaders Chelsea but have a game in hand, with a massive trip to Old Trafford on the horizon this weekend.
"That's probably the best way to approach any match - to have an aggressive stance from start to finish," Allen told the official Liverpool magazine.
"Some people might argue against that and be happy to shut up shop at 1-0 or 2-0.
"But I feel that if you try to do that, you're always giving the opposition a chance to get back in the contest.
"With teams like Arsenal, for example, you don't want to give them any opportunity to do that. In many ways, that was why it was such a perfect display."
Speaking about that famous win at Anfield last month, the 23-year-old also said he has not seen a better performance than during the opening 20 minutes, which saw Liverpool go 4-0 up within the blink of an eye.
"I don't think I've seen a better performance in 20 minutes of football from the first whistle," he said. "Our target now is to make sure we do that in every game.
"Obviously it's difficult to play to that level all the time, but that's our dream and what we're aiming to do. How clinical we were with the ball and how many chances we created was one thing.
"But with Arsenal being such a great footballing team as well, the way we stopped them playing and won the ball back and pressed them hard was equally as pleasing."
Rodgers' men are currently the highest scoring side in the Premier League with 73 goals which is more than Bayern Munich at the top of the Bundesliga and marginally behind Real Madrid and Barcelona in La Liga.
Are Liverpool better off sticking to their attacking approach?
