"The body is a little sore as you would expect, but I'm looking forward to having another opportunity against these guys and come tomorrow night, back out here on my home pitch in front of our fans, I know those guys will get me up," Messam said.
"It's a once in a lifetime opportunity to play these guys and I'm lucky enough to get two cracks."
The Chiefs will fancy their chances against the Lions due to the fact that Warren Gatland has named effectively a B team ahead of Saturday's first test against the All Blacks at Eden Park, and their extra preparation time compared with the Maori who were together for less than a week.
Dave Rennie's men will have watched as the Lions have refined their game plan over their past five matches and will know that Gatland's shadow test side has nowhere near the power in the pack his top team does.
The Chiefs will likely gain parity or even have an advantage in the scrum, as the Highlanders did. If they do that and nullify the Lions' lineout drive, anything can happen.
In commenting on the Lions' 32-10 victory over the Maori, Messam said: "They played really well in the second half against us. They trapped us in our own half and strangled us, really."
But he also added: "The Maori only had a short preparation. I know our guys have been training really well to handle those sorts of situations."
Gatland may be keeping an eye on the first test, but his Lions team are on the brink of another significant challenge.
Before Messam eased his frame off the chair, he couldn't resist a question about captain Stephen Donald's engagement, revealed by Gatland, which apparently consisted of a whitebaiting expedition and the presenting of a ring near the back of Donald's ute.
"I think they're going to write another movie about him...," Messam said. "No, good on him, it's about time he grew up."
