An embarrassing performance last night was compounded by a track side bust up between Kris Commons and the coaching staff.

Kris was not happy at being substituted as Celtic looked for a way back into the game and vented at the manager before arguing with assistant coach John Collins in public.

This has split many Celtic fans, many saying he was right to show passion even if it was in full view while others say he should have kept it in the dressing room.

What do you think?
