Karim Adeyemi fires hat-trick as Borussia Dortmund demolish Celtic

The Champions League has a habit of inflicting these inglorious episodes on Celtic. It is difficult to shake the notion that this big fish simply cannot swim when removed from its small domestic pond. Borussia Dortmund toyed with and teased their visitors in a match that was over as a contest long before the half-time whistle blew. The Germans have won two out of two in this new format, having been barely tested over 180 minutes. They will have aspirations of equalling last season’s memorable tournament run.Suddenly there is pressure on Celtic’s upcoming trip to Atalanta. The paucity of their showing here undermined what had been a widespread sense Celtic were better equipped for the Champions League than at any point in recent seasons. Theirs was a fragile, error-strewn display.
