While Arsenal have been grabbing the headlines for a finely-tuned approach, United have also been going about their own game with a certain panache - smashing four goals in each of the last four matches before Saturday.
With the likes of Carlos Tevez, Ronaldo, Rooney, Anderson, Nani and Ryan Giggs at the disposal of Sir Alex Ferguson, England midfielder Hargreaves is in no doubt of just what this side can do on the pitch.
"Arsenal kept the ball and had a lot of possession, but they were never really threatening. Football is about scoring goals and winning games," said Hargreaves, now fit again following a niggling knee problem.
"I do not think they had a clear-cut chance created in the first half, apart from the header by Gallas, and that was a set piece.
"Defensively, we did a good job and tried to control their so-called beautiful football."
Hargreaves added: "They keep the ball and try to play that way, but when a team is as good defensively as ours, you can keep them at bay because we played very tight together.
"You do not get to the top by conceding a lot of goals, but it is difficult when there is so much offensive power on the pitch.
"When you win the ball back against a team like Arsenal, who take a lot of risks going forwards, is vital that you attack.
"We have a lot of quality going forwards to catch them.
"Both of our goals were from really beautiful pieces of play and theirs were a bit more scrappy."
