Manchester City boss Roberto Mancini has reportedly banned his team from playing music in the club's dressing room.
It is believed that the Italian coach came to the decision in order to prevent his senior players from getting distracted from their fight to win the Premier League title.
"The manager won't allow any music because he feels it distracts them when they should be concentrating," the Daily Star quotes a club source as saying.
"The players are not happy with the decision. Many of them use music to get psyched up, particularly in the big matches."
Man City dropped a point below league leaders Manchester United following a 1-0 defeat to Swansea City at the weekend.
