United entertain Real Madrid in a Champions League last-16 second-leg clash tomorrow 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," said Giggs.
"When you have that much firepower on the pitch, undoubtedly there are going to be chances and goals."
And the spectre of Ronaldo remains. Only this time it is the man who once delighted the Old Trafford faithful rather than the one who remains the highest goalscorer in World Cup history, whom Ferguson rather cruelly dismissed today.
"The older one, the fatter one, peaked as a centre forward at that time," said Ferguson.
"(Cristiano) Ronaldo is a supreme athlete. He never misses a game, has fantastic physique, two great feet, pace, he is good in the air.
"My biggest concern is if he turns up because you expect problems.
