Can 'perfect' performance be 'transformative' for Celtic?
It's all about Celtic on the BBC's Scottish Football Podcast the morning after a triumphant Champions League night.
Former midfielder Scott Allan and The Scotsman sports editor Mark Atkinson look back at the sensational 5-1 win over Slovan Bratislava and analyse what it means for their Champions League campaign going forward.
Record signing Arne Engles was a standout against Bratislava, and Atkinson says the Belgian's seamless start to his Celtic career means the team aren't missing Matt O'Riley.
