Part of the Lions team that downed New Zealand 24-21 in Wellington last Saturday, Furlong was also in the Ireland side that beat the All Blacks 40-29 in Chicago last year.
That victory, Ireland’s first ever over the New Zealanders, sparked a furious response from the world champions during the return fixture in Dublin.
NZ ran out 21-9 victors, conceding 14 penalties and picking up two yellow cards as they bludgeoned the men in green into submission.
Furlong predicts a similar reaction at Eden Park after the All Blacks’ forwards were outmuscled in Wellington.
He says: “I remember coming off the pitch and being absolutely shattered. I was sore for days after it.
“It was one of the most brutal Test matches I’ve played in my short career. I think everyone will expect that and try and tee themselves up for it.”
