Linfield boss David Healy and captain Jamie Mulgrew have urged fans to steer clear of discriminatory behaviour after sanctions against the club by the IFA.
Healy said “racism or sectarianism has no place in the stands”.
“Our success as a team is not just measured on the pitch, but also the strength of our fanbase,” said Healy.
In a video posted by the club, he added: “Your passion, dedication and unwavering support are the driving forces that motivate our players and myself to give our all in every match.
“And for that, I want to thank each and every one of you. But as we embark on this journey, I must address a crucial matter. Our game is no place for racism or sectarianism.
“We as Linfield supporters have a responsibility to uphold the values that make our football club a unifying force. Our differences should be celebrated, not used as a means to divide us.
“Racism or sectarianism has no place in the stands, on social media or anywhere else associated with our beloved club. We are here to support Linfield and that means supporting each other as well.”
‘We want everyone to feel welcome at Windsor’
Linfield were given a one-match stadium ban for away spectators, suspended until 29 February 2024, with the IFA saying the sanction can be implemented with immediate effect if another incident of spectator misconduct occurs before that date
Sectarian chanting from Linfield fans occurred during the matches against Larne at Inver Park on 15 September and against Cliftonville at Solitude on 20 October.
They were also sanctioned for a racist comment from a supporter their game at Windsor Park against Loughgall, which was directed at visiting player Pablo Andrade.
Linfield, who had the right to appeal the sanctions, were fined £1,000 for what happened against Larne, £2,000 for the Cliftonville match and £1,000 for the Loughgall game.
“Let’s be clear: anyone behaving in discriminatory behaviour will not be tolerated,” added Healy.
“We want every fan, regardless of their background, to feel welcome at Windsor. Our unity is the Linfield way and we cannot let anything jeopardise that.
“I have full confidence in each and every one of you to continue to be the incredible supporters you are. Let’s make this season unforgettable both on and off the pitch.”
Speaking in the same video, Linfield captain Jamie Mulgrew echoed Healy’s comments and urged fans to report incidents of spectator misconduct.
He said: “We do have fantastic supporters who follow us week in, week out and send us positive vibes. If you ever hear any of these things spoke about or shouted, in the stands or on social media, it is vitally important that you report it to an official from the club.
“As I say, that is completely unacceptable behaviour and is not a positive or good representation of what this club stands for.”
In a statement that accompanied the video, Linfield chairman Roy McGivern warned supporters that further instances of spectator misconduct could lead to a points deduction.
Linfield are currently top of the Irish Premiership as they head into a busy festive period that includes home games against Coleraine on Friday and Glentoran on Boxing Day, and trips to Larne on 30 December and Crusaders on 2 January.
