Adam Jones' knee problems prompted Warren Gatland to call up Lee as cover and despite his tender years, North is convinced he has all the attributes to succeed should he be called upon during Wales' four autumn internationals with Argentina, Samoa, New Zealand and Australia.
"I think physically, yes [he's ready for international rugby]. He's a monster, an absolute monster," said 20-year-old North, who won the first of his 24 caps aged 18.
"Samson is immense. I don't think anyone knows actually how good he could be and he's tearing it up at the moment.
"So he's a player that I wouldn't mess with, personally.
"I'm glad he's on my own team because he's a hard nut.
"But it's good for him, obviously. It'll be great experience for him to come and train in this environment and get a few caps under his belt."
