Argentina coach Jorge Sampaoli has taken a swipe at Arsenal attacker Alexis Sanchez.
Sampaoli worked with Alexis as Chile coach.
Alexis has a reputation for being fiery and determined and is often praised by fans for his on-the-field attitude.
However, when he is not playing, Sampaoli has claimed he is a very quiet and shy member of the squad.
In an interview with Ultimas Noticias, the 57-year-old said: “He sometimes gets up with his headphones on.
“He sits alone to have breakfast and doesn't talk with anyone."
