Swansea City boss, Paul Clement, believes the rise of "player power" is taking football to "dangerous ground".
Swans host Middlesbrough on Sunday, who recently sacked boss Aitor Karanka amid talk of rows at the Boro training ground.
Ahead of a vital relegation clash, Clement said it was an unwelcome development.
"You hear stories of players (getting) into (the ears) of owners, that is dangerous ground," said Clement.
Clement's Swans also beat Leicester in what turned out to be Claudio Ranieri's last game in charge in the Premier League after the Italian was sacked amid rumours of dressing room discontent.
