54 of 100: Circle of Truth and Lies

Logic Level 2

On a certain island there live only knights, who always tell the truth, and knaves, who always lie.

One day you find 10 island natives standing in a circle. Each one states: "Both people next to me are knaves!"

Of the 10 in the circle, what is the minimum possible number of knights?

Remember you don't want just any configuration, but one that has the minimum number of knights.
