Irish League champions Linfield FC have launched a new anti-sectarianism campaign in an attempt to attract more families to matches at Windsor Park.
Linfield players helped launch campaign
The aim is to allow spectators to enjoy games without hearing offensive chants.
The club said all of its staff are backing the "True Blues" project. Many of its players attended the launch on Saturday afternoon.
From now on anyone caught making racist or sectarian comments could be arrested, prosecuted and banned.
"It's a very, very small minority we're looking to shut up," Linfield manager David Jeffrey said.
"We're only looking to shut them up in some of the bigger games, because they don't go to the smaller games.
Linfield manager David Jeffrey wants only "true supporters" at ground
"What we're saying to them is 'if you want to come and support Linfield, fantastic - we want you here supporting the club, but we want you supporting the club in the right way'.
"'Remember, the team that you're supporting is a team that consists of players from all sides of the community'."
The initiative is based on guidelines published by UEFA, the sport's European governing body, but Linfield's management insisted it is about more than obligation.
