Twenty years and three days after his first FA Cup goal, Giggs' strike was his 12th in the competition.
"It means a lot," said Giggs. "We've not done as well as we should have done in the last eight, nine years.
"There's a lot of players desperate to win it. With the history we've got in the competition, we should be there, we should be getting to finals, so hopefully this will be the year."
