Celtic host Besiktas on Thursday following a disappointing Premiership loss to Falkirk. The Scottish side has failed to win any European match this season and face elimination from continental competition if they cannot overcome the in-form Turkish outfit. Besiktas arrive at Parkhead unbeaten in the competition, with victories over Marseille and Hoffenheim plus a 2-2 draw against Crystal Palace.
Manager Martin O'Neill is anticipated to deploy a 4-2-3-1 formation. Sam Johnstone continues in goal despite a lack of clean sheets. Colby Donovan is set for the right-back role with Alistair Johnston unavailable, while Kieran Tierney's fitness concerns may force Jordan Lotomba into action at left-back. Cameron Carter-Vickers and Liam Scales anchor the defence.
Mika Baur drops deeper to form a midfield pivot with Callum McGregor against Besiktas's physical presence. Benjamin Nygren returns to the starting eleven as an advanced playmaker. Haissem Hassan and Callum Osmand operate as wide attackers, with Camilo Duran leading the attack. James Forrest and Sebastian Tounekti are options from the bench.
