UCL last-16 draw: Real Madrid face PSG after redraw required due to UEFA errors

Real Madrid will face PSG in the 2021-22 Champions League round of 16 after the ties had to be redrawn on a chaotic and embarrassing afternoon for UEFA.
The two European heavyweights will clash next year in the pick of the ties, with reigning champions Chelsea facing Lille – who they also were paired with in the original draw.
Manchester United – who were originally against PSG – will face Atletico Madrid, Manchester City are against Sporting CP and Liverpool will take on Inter.

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.
