The Red Devils thrashed Fulham 5-0 at Craven Cottage last night to keep the pressure on leaders Manchester City, and sit two points behind their rivals going into the Christams period.
"It's been a good few weeks," Giggs told MUTV. "You saw what we're capable of [at Fulham] and that's the standard we set ourselves.
"It was a similar story at Queens Park Rangers [last Sunday]. There, we just didn't finish the chances off. Today we managed to score the goals.
"To come to a place like Craven Cottage and have that sort of movement and interplay was first-class."
Sir Alex Ferguson's side welcome relegation-strugglers Wigan Athletic and Blackburn Rovers to Old Trafford over the festive break, and the 38-year-old sees it as a perfect opportunity to pick up maximum points to keep their momentum.
"We have to carry on the form we're in at the moment. If we do that we're a very hard team to beat, especially at home," added Giggs. "At Old Trafford we always expect to go out and win but we still need to go out with the same hunger and appetite as we had [at Fulham].
"For myself and Michael Carrick in midfield, the movement in front of us was brilliant. Obviously the defending was good as well. But when you have so many options on the ball – people running in behind, people dropping in the hole – we're a very difficult team to play. The performance was really pleasing."
Giggs netted United's third goal of the game, with the help of a sizeable defelction, to open his league account for the 2011-12 campaign - a feat which now means the Welshman has scored in each of the past 22 Barclays Premier League campaigns.
"I was starting to get worried [I wouldn't score this season," Giggs revealed. "Last season I scored in one of the first games so I didn't have to worry about it after that.
"I'll definitely be claiming this one. A centre-forward would definitely claim it."
