"It's actually crazy how fast Frida is going at the moment," says Andersson.
"Now I started a minute before her and I saw her coming through a few sections. Then it looked a little like she was flying ahead. You can't help but be impressed," she continues.
Frida Karlsson repeated her skiathlon performance and completely crushed the opposition in the 10-kilometre race. Once again it was Ebba Andersson who took the silver medal, 47 seconds behind Karlsson.
"Things are going well now," says national team manager Anders Byström after another Swedish medal double in Olympic skiing.
Byström continues on SVT's broadcast.
"She (Frida Karlsson) has been good for a long time, but the level she has reached now is something special," he says.
"In good shape, skis technically perfectly and is so relaxed."
Sweden has so far won seven of nine Olympic medals in women's cross-country skiing.
