Ireland captain Rory Best closes in on century of international caps

"I think it's probably safe enough to say I didn't ever anticipate this."

Best will become Ireland's fifth centurion in Saturday's autumn Test clash with Australia in Dublin, joining Brian O'Driscoll, Paul O'Connell, Ronan O'Gara and John Hayes in the exclusive set.
