As regular as clockwork at around the 75min mark (but as an AB fan I don't mind that ).
Overall, I don't mind DBG at all. He's pretty good at his job - knowledgeable and does his homework. Maybe he should describe the play more. Is there too much expected of commentators to be wits and raconteurs? This is where they go wrong IMO (DBG not the worst for this), nobody follows a football match to be exposed to one guy's 'unique' sense of humour. Good-humoured yes, but humorous? Not so much
