The Ibrox legend succeeded Walter Smith as manager last summer, but saw the SPL title ripped from his grasp as the club were plunged into administration.
McCoist has emerged as a shining light for players and fans to rally behind in their hour of need and Goian is confident his gaffer will have his moment of glory in the future.
He said: "He tried to explain to everyone exactly what admin-istration means because, to be honest, in the beginning I didn't know.
"The first couple of weeks were difficult, but we stayed together and we made the decision for the club and for everyone. Ally is a good coach, a good man and he is really loved here.
"I am sorry for him we didn't win the cham-pionship this year.
"We are confident that next year we are going to win it and he is going to win a championship as a coach."
Goian has impressed at the heart of the Gers backline alongside fellow summer signing Carlos Bocanegra this season, but his future in Glasgow is uncertain.
The Romanian has no qualms about making the switch from Palermo last year, however.
He said: "I came here because when my agent told me about Rangers he said that every year you are fighting to win something – the championship or a cup – and every year you are at the top. I wanted to come here."
