Celtic secured their first Europa League win of the campaign at Parkhead on Thursday, overturning a 1-0 deficit against Besiktas thanks to an inspired double substitution from manager Martin O'Neill. Facing the prospect of a fourth straight European defeat after an hour of play, O'Neill introduced Callum Osmand and Camilo Duran in place of James Forrest and Sebastian Tounekti. The impact was instantaneous, as 20-year-old Osmand found the bottom corner of Alexander Nubel's goal with his first touch just 43 seconds after entering the pitch.
The turnaround gathered pace in the 77th minute when O'Neill withdrew Kasper Hogh and moved Duran into a central attacking role. Osmand quickly supplied the Colombian with a delightful pass, allowing Duran to round Nubel and slot Celtic into the lead. Although Orkun Kokcu equalised for Besiktas with a fine strike, Duran delivered the winner two minutes later by controlling Kieran Tierney's scuffed shot and scoring from close range. Duran became the first Celtic substitute to score twice in a European match since Johannes Edvaldsson against Jeunesse d'Esch in September 1977.
The display from the bench highlighted the contrasting form of Celtic's attackers, especially regarding Hogh, the club's £11m record summer signing from Bodo/Glimt. Despite working hard, the Danish forward registered zero shots and only one touch inside the Besiktas box across 77 minutes, extending a difficult start that has seen him fail to score in 16 of his 17 Celtic appearances. In contrast, Duran produced four box touches, two shots, and two goals in just 30 minutes, with former midfielder Stiliyan Petrov noting on TNT Sports that the changes also liberated key space for Nygren and Baur.
Addressing his lineup choices following a demanding stretch of nine games in 25 days, O'Neill explained that the substitutions were part of the tactical plan to inject fresh energy, adding that Duran has been fabulous all season regardless of where he plays. Former Fulham attacker Osmand also praised Duran's poaching ability after their decisive contributions. With Duran demonstrating his threat through the middle and Osmand pushing for a starting role on the left wing, O'Neill faces intriguing selection choices ahead of upcoming high-stakes fixtures.
