The Champions League last-16 draw descended into chaos on Monday after Manchester United were accidentally drawn against group rivals Villarreal, and omitted from being drawn against Atletico Madrid.
United qualified for the knockout stage of this competition after coming through their group that contained Villarreal, Young Boys and Atalanta.
The draw for the next round took place in Nyon, Switzerland on Monday where former Arsenal star Andriy Arshavin was tasked with drawing the remaining 16 teams from the pot.
However, UEFA chief Giorgio Marchetti was forced to intervene midway through the draw after United were pitted against Villarreal.
