REF’s picks

Besiktas arrive in Glasgow sitting comfortably in the top eight of the Europa League table and look well-equipped to punish a struggling Celtic side. The Scottish hosts are still searching for their first points in the league phase and have looked vulnerable at the back, missing key figures like Cameron Carter-Vickers. While Celtic Park will provide a hostile atmosphere, the visitors' superior European momentum makes an away win the value play.

1. 1Besiktas have taken seven points from their opening three games and boast proven continental goalscorers.
2. 2Celtic are without influential defender Cameron Carter-Vickers and have lost three of their last five matches across all competitions.
3. 3Away fixtures in Glasgow are notoriously difficult, and Besiktas have occasionally stumbled domestically when heavily favored.
