Celtic faced a tough outing in the Europa League, suffering a 4-1 defeat against Benfica in Lisbon. Despite a spirited second-half effort, the visitors were ultimately outclassed by their hosts, who capitalized on defensive errors to secure a commanding lead.

Jhon Duran opened the scoring with a cool panenka penalty in the 5th minute, following a foul by Dane Murray. The lead was doubled in the 23rd minute when Alexander Bah volleyed in a well-placed cross from Gianluca Prestianni. Duran then made it three in the 36th minute, capitalizing on a mix-up in the Celtic defense to score from an acute angle.

Celtic's Camilo Duran, who had just welcomed a child, managed to pull one back in the 63rd minute with a header from a cross by Haissem Hassan, demonstrating the potential for a comeback. However, Vangelis Pavlidis sealed Benfica's victory with a goal in the 89th minute.

Key moments included:

• 5th Minute: Penalty awarded to Benfica.
• 36th Minute: Duran scores from an impossible angle.
• 63rd Minute: Camilo Duran's goal gives Celtic hope.
• 89th Minute: Pavlidis scores to finalize the score at 4-1.

Despite Celtic's misfortunes, including hitting the woodwork multiple times, defensive frailties proved decisive. This result leaves Celtic with two defeats in their opening games of the league phase, raising concerns about their defensive stability as they look to bounce back in upcoming fixtures.
