UEFA have declared the draw for the Champions League last-16 'null and void' following an error which meant Manchester United were left out of part of the process.
There was initial confusion with the original draw when United were pulled out to face Villarreal - however, this was not possible given the two teams had faced each other in the group stage.
United's rivals City were then drawn out to face the Spaniards, however, the ball with United's name was not included as a potential opponent for Atletico Madrid, who instead drew Bayern Munich.

"As a result of this, the draw has been declared void and will be entirely redone at 15:00 CET."
