Erik ten Hag will be expecting a response from his Manchester United players after their disappointing exit from the Europa League, and while his focus will have quickly switched to Sunday's FA Cup clash with Brighton, the midweek debacle will be difficult to forget.
Having taken a 2-0 advantage in the first leg at Old Trafford last week, the Reds were cruising towards the semi-finals. However, when Tyrell Malacia put the ball into the back of his own net, it quickly became clear that things were about to take an unexpected turn.
Harry Maguire - having come off the bench at half time - became the second Reds player to score an own goal as the home side somehow squandered a two-goal advantage.
United had gone from travelling to the Ramon Sanchez-Pizjuan Stadium with a 2-0 lead in the bank to needing a victory away from home in a tricky environment.
