United entertain Real Madrid in a Champions League last-16 second-leg clash on Tuesday knowing a goalless draw will be enough to clinch a quarter-final berth.
Manager Sir Alex Ferguson does not think that will happen, though, considering the strengths of both sides lies in their attack rather than defences which have rarely been watertight this season.
It is just one of the reasons to look back on Real's last visit to old Trafford, an amazing occasion that finished 4-3 to United thanks to two goals from David Beckham and a comeback that followed a hat-trick from Brazilian forward Ronaldo, which earned him a standing ovation from the Stretford End.
"It was two great sides and there were so many goals. It could be similar tomorrow [Tuesday]," said Giggs.
"When you have that much firepower on the pitch, undoubtedly there are going to be chances and goals."
Although Phil Jones is set to miss the tie due to injury, it is generally wise not to take Ferguson's injury bulletins ahead of such an important game as gospel until the teams are actually confirmed, the United boss does face a dilemma over who will replace him in midfield.
Tom Cleverley has a claim, although his natural instinct is to push forward rather than screen a defence, as does Wayne Rooney, especially if Ferguson opts for a more attacking wide player in the form of Nani or Ashley Young.
Giggs is more likely than either, though, given his vast experience and present form.
The Welshman's recent displays mirror those of Real as a team, given they flew into Manchester on Sunday night following back-to-back wins over Barcelona, the first of which in particular - a devastating 3-1 Copa del Rey second-leg triumph at the Nou Camp following a 1-1 stalemate at the Bernabeu - creates an uncomfortable precedent United need to avoid.
