It was hugely disappointing when the Reds succumbed to the Spanish side 2-1 on the night, and on aggregate, with the outcome never in doubt after Wissam Ben Yedder came off the bench to score two priceless away goals. United managed only three shots on target all game, one of which was Romelu Lukaku's consolation effort.
This followed a goalless draw at the Ramon Sanchez Pizjuan Stadium when David De Gea was Man of the Match and only one shot on target was mustered by the visitors.
It is important to note that it is not unusual for matches in the Champions League knock-out stages to be tight but it felt like a pretty meek way to exit the competition.
