Arsenal boss Arsene Wenger admits social media is an unwelcome headache for Premier League managers.
Wenger was asked about Liverpool striker Mario Balotelli's Instagram controversy this week.
"We can offer our players only a warning of the potential danger," said Wenger. "You cannot, however, keep an eye on a player 24 hours a day.
"They must be responsible and mature enough to keep themselves in check.
"The danger of social media is that you do not dwell on the consequences of what you say."
