Celtic Park was almost full to its 60,000 capacity and the former Celtic player and manager took charge of the Petrov XI.
Like Martin O'Neill, Dalglish has also stood strong beside his wife as she has fought cancer.
And the admiration for the way Petrov has come to terms with being another victim of a condition which does not discriminate over age, wage or physical fitness dripped from every heartfelt word of praise.
He said: "I think everyone enjoyed the game.
"The support he has had, first and foremost from his family, but also from the footballing family, at Aston Villa and Celtic, has been unbelievable.
"The reception they gave him was a fitting tribute to a very strong man who is an example to everyone else who gets a bit of bad news.
"There was hardly anybody who left the ground, they were there at time-up to applaud him.
"Every time somebody at this club gets a bit of bad news the support from the fans and club is always more than generous.
"The turnout was fantastic and a fitting tribute to a really brave man.
"The harder you stand up for yourself and the stronger you are in the fight against it, the better chance you have of succeeding.
"He is an inspiration for what he has gone through. He never moaned or complained, he tried his best to get through it."
