Such is the majesty of Pep Guardiola's Spanish champions that they have changed the landscape of the competition. They have beaten United twice in recent finals and beaten them well.
Giggs said: "Teams have beaten them. We beat them three years ago in a semi-final when they were not too different.
"What they've got now is more experience and confidence from winning things but we've got to overcome that if we come up against them again. We've got to get better. I'm sure we can with the players we have."
