Manchester United would have played Paris Saint-Germain in the Champions League last-16, a fixture which would have seen Cristiano Ronaldo and Lionel Messi face off, before it was announced that a re-draw will take place.
A number of mistakes during the first draw at 11am this morning forced UEFA to take unprecedented steps, with the whole round of ties to be done again at 2pm.
United were pitted against group rivals Villarreal, a tie against the competition's rules, and they were later omitted from being paired against Atletico Madrid.
However, had the initial draw been allowed to stand - despite the controversy and backlash from clubs - the star-studded, blockbuster tie between the Old Trafford side and PSG would have been the pick of the action.
