The Welshman turns 40 on Friday and will enjoy the day a little more thanks to a stunning 5-0 win at Bayer Leverkusen.
It was United's biggest ever away win in the Champions League and was given to them thanks to goals from Antonio Valencia, Emir Spahic (own goal), Jonny Evans, Chris Smalling and Luis Nani.
"I think our speed (was the difference)," Giggs told Sky Sports 2 after a masterful performance in central midfield.
"The first goal was a good example; quick play. It was a pleasure to play behind our front four."
Giggs still saw improvements, though, no matter how unconvincing he sounded as he expressed them.
"We could have scored more," he said.
"But we can't be too greedy. To score five anywhere in Europe is a great result.
"Going into a game knowing a win puts us through is a carrot and the five goals and a clean sheet is a bonus.
"It was a pleasure."
United manager David Moyes admitted it was the best performance of his brief reign so far.
"I'd probably have to say it is," he said.
"I hope I can continue the standards of before (under Sir Alex Ferguson). Tonight showed that. Qualification is expected, as is to do well in the league and cups.
"(The performance) is what I've been hoping to get more often - I've not had it as as often as I'd like."
On Giggs he added: "People will question his age but you can't question him as a player. He was fantastic with everything. He did his job with no fatigue for his age.
"There were so many good performances. To come to Germany and get such a good result... They're second in the league and it gives you an idea where our performance and result was."
