Champions league round of 16 draw: all you need to know about why another draw was taking.

Champions league round of 16 draws took place after error involving Atletico Madrid Liher pool and Manchester United.

Manchester United were not put into the pot of group winners after runners-up Atletico Madrid were drawn, while Liverpool were also mistakenly put into the pot to potentially face Atletico despite playing them in the group stages

UEFA conducted a new Champions League last-16 draw at 2pm after a mistake involving Atletico Madrid, Liverpool and Manchester United. UEFA said a "technical problem" was to blame and resulted in the original draw being declared void. The issue arose when Group B runners-up Atletico were drawn and their possible last-16 opponents - all group winners - were then put into a separate pot, but United were not included.Teams who met in the group stages are supposed to be kept apart in the last-16 draw. United did not face Atletico in the groups, but Liverpool did, and Jurgen Klopp's side were mistakenly put into the pot to potentially face Atletico - who were then drawn against Bayern Munich.

The original draw had seen United set to play Paris Saint-Germain, while Liverpool had been drawn against Salzburg.

UEFA said in a statement: "Following a technical problem with the software of an external service provider that instructs the officials as to which teams are eligible to play each other, a material error occurred in the draw for the UEFA Champions League Round of 16.

"As a result of this, the draw has been declared void and will be entirely redone."

Manchester City boss Pep Guardiola believes UEFA has made the correct decision to repeat the draw.

Speaking at a press conference to preview his side's game with Leeds on Tuesday, Guardiola said: "I think it is fair. It was a mistake but sometimes these things can happen.

"If there was a mistake you have to repeat so it is not suspicious."
