The Colombian's performance was a highlight in an otherwise frustrating week for the club, which saw them squander a four-goal aggregate lead in Thursday's 5-1 defeat by LASK in the Champions League qualifiers. Celtic fans responded by mocking the club's "world class" claims with banners listing teams who have beaten Celtic in the Champions League qualifiers in the past 14 years.
Durán's goals, scored in the opening 29 minutes, were set up by his teammates, and he also set up several chances for them. Falkirk improved after the break and were rewarded by Colby Donovan's own goal in the 72nd minute. The win was a much-needed boost for Celtic, who will look to build on this momentum in their upcoming matches.
Celtic's next match is against Rangers, who visit Aberdeen in a noon BST kick-off on Sunday. Rangers were eliminated from the Conference League on penalties by Jablonec three days ago, and will be looking to bounce back from this defeat.
