Dashing defender Harry O'Brien spoke to CTV about his role in Collingwood's nail-biting six-point victory over St Kilda on Saturday night.

O'Brien was pitted against St Kilda champion Stephen Milne in a battle that, as has so often been the case, was one of the most enthralling of the match.

The 25-year-old discussed the challenge of playing against the livewire Saint and pondered the fluctuating fortunes of the team in a game that saw the ascendency seesaw all night.

“Bucks congratulated us on getting the win, but we also had a long discussion on how we can improve, how we can play so good in the second quarter and then drop off in the third and really get them back into the game”.
