Rangers have condemned "so-called fans" who rampaged through Glasgow at the weekend.
The conduct of some supporters has been heavily criticised after thousands descended on the city on Saturday to celebrate the club's Premiership title win.
Several arrests were made amid scenes First Minister Nicola Sturgeon branded "thuggish and selfish" as the occasion spilled over into disorder and violence.
Large numbers of supporters gathered at George Square despite pleas from Rangers and the Scottish Government to follow Covid-19 restrictions.
The Ibrox club have now accused a "small minority" of bringing shame on their reputation and branded their behaviour "unacceptable".
A statement said: "Winning our 55th league title in our 150th year was a historic day for Rangers Football Club. The support from millions of our fans across the world has been incredible.
"The achievement by Steven Gerrard and his team has received plaudits from across the football family, including recognition by sports writers, opposition players and managers.
"We are grateful to Scottish Government officials, Glasgow City Council and Police Scotland for the constructive engagement in the lead up to the weekend's game. We worked closely with the authorities for two weeks before Saturday's match to ensure a consistency of message.
"Sadly, a small minority of people behaved inappropriately and in a manner not reflective of our support. Some of the scenes were unacceptable and have besmirched the good name of Rangers Football Club. These so called "fans" should reflect upon the values and ethos of our club, and consider the damage this does to the reputation of the club.
"We will continue to engage with authorities as required."
