United were finally held to a draw against Paris-Saint Germain, but several clubs have complained to Uefa that the integrity of the draw results was destroyed by mistake.
“Following a technical issue with an external service provider’s software instructing officials on whether teams were eligible to play against each other, a critical error occurred during the Round of 16 draw. Uefa Champions League,” a Uefa statement confirmed.
“As a result, the draw results have been declared void and will be completely re-executed at 1500 CET (2pm GMT).”
Initially, United were held to a draw against Villarreal, a draw that could not have been played as both teams advanced from the same group, and Giorgio Marchetti, Uefa’s deputy general secretary, discovered the mistake and ordered it redraw the game.
However, a technical error later appeared to prevent United from qualifying to face Atletico, the next team being held to a draw.
Real Madrid, who received a favorable draw against Benfica, reported that the draw was only replayed from the time of the error, with their draw already decided before it was made, but Uefa has now declared the previous draw to be void in its entirety.
