Manchester City manager Pep Guardiola has labelled team leaks as "unethical and unprofessional".
There are growing concerns over leaks after Jack Grealish's surprise absence got out ahead of Aston Villa's eventual loss to Leicester City.
The leak came after Villa players and staff took Grealish out of their Fantasy Football team prior to kick-off.
Speaking about the issue, Guardiola said: "Sometimes when you have a team selection and people have friends from other teams, they talk about what they do.
"Sometimes it happens and it's incredibly unethical and unprofessional but can't be controlled."
