Ali Price has warned his Scotland team-mates not to overlook "dangerous" Tonga in their opening autumn Test at Murrayfield on Saturday.
After impressing on the Brtish and Irish Lions tour in the summer, Price will co-captain the Scots alongside Jamie Ritchie.
Tonga famously stunned Scotland in a 21-15 victory in 2012, and Price says that memory serves as a warning.
"They're a dangerous side," said the Glasgow Warriors scrum-half.
"People can be quick to look at recent results and feel like it's a foregone conclusion, that we just have to turn up (to win).
"But if you watch their previous performances at World Cups, they pushed France close, they're a very competitive team with some brilliant individuals who can create something out of nothing. They are physical, strong runners.
"We need to put in a professional performance, we know that. Focus on ourselves, get our processes right and hopefully that leads us to the correct result."
