Derek Johnstone has blasted the Brondby "hooligans" who stormed the Rangers end during Thursday's clash in Denmark.
Steven Gerrard 's team played out a 1-1 draw that dented their prospects of making the Europa League round of 16.
But the game was overshadowed for long spells by crowd trouble, with some home fans reported to have rushed the Rangers end of the stadium.
The violent scenes cast a shadow over the game and now Johnstone, who was in attendance, has offered his view.
Writing on Instagram, the former striker - who scored 212 goals in total for the Ibrox club - blasted the "hooligans" who are said to have attacked the Corporate seats in the Rangers end.
He says he has "never seen" such behaviour in his 50+ years in football.
Johnstone wrote: "Copenhagen is a beautiful city with plenty of cafes and things to see but sadly it was spoiled by a couple of dozen local hooligans who decided to attack the Rangers Corporate seats in the stand, along with a few other Rangers supporters.
"In all my years in football I have never come across such disgraceful behaviour.
"In the end the Gers thoroughly deserved the point away from home and it easily could have been three."
