Why were the ties redrawn?
The draw for the last 16 had to be redrawn after a mistake resulted in the original ties being declared null and void.
Manchester United were originally placed with Villarreal, however, this was an error as they were in the same group. They were then wrongly not included in the pot for the subsequent tie.
PSG were then drawn with Man Utd – which would have seen Cristiano Ronaldo and Lionel Messi face off – however the entire draw was cancelled and redrawn.
