Manchester United's Casemiro and Facundo Pellistri are both at risk of missing the Reds' potential Europa League semi-final first leg.
The duo both sit on two yellow cards each meaning that another caution in Seville would see them miss United's first game in the Europa League semi-finals against either Juventus or Sporting, should they get past their Spanish opponents in the quarter-finals.
Erik ten Hag's team looked to be in a good position to progress to the next round of the competition when Marcel Sabitzer scored twice in the first 45 minutes.
