Real Sociedad boss David Moyes has warned his players about leaks to the press.
The former Manchester United and Everton manager has made it clear he won't tolerate 'moles' inside the locker room.
El Confidencial says Moyes told his squad that "he who leaks to the press will be kicked out of this club and onto the street".
The Scot has also closed training from the public to keep his tactics a secret from opposition scouts.
