Owen Heary and Karl Moore soldiered in the trenches together for many games but it's a different relationship now.
Moore's still soldiering while Heary in his new role as manager must organise the troops and devise the battle plan.

98FM Sport's Stephen Doyle caught up with both men ahead of the 7:45 kick-off and Heary doesn't expect a friendly welcome for former Bohs full back Luke Byrne.
