I've never understood this "inside information" concept. Most sport is played in public, where anyone can watch it.
For argument's sake, what "inside info" could Lovren give about Liverpool players?
"Yeah, Lucas. He's quite slow. Can be exploited by running at him. Sakho is prone to coughing up possession in dangerous areas."
What could he tell anyone that isn't entirely obvious already?
Good point. Maybe who the leader in the dressing room is, and how to psychologically break him.
