Replays clearly showed the Scotland international had been brought down in the CSKA penalty area.
The former Scotland boss said: "This (appealing against yellow cards) is something that was brought up at a UEFA meeting a couple of years ago I was at with a lot of the top coaches.
"That was a topic back then because there are a lot of injustices. The Darren Fletcher situation was ridiculous. There are so many things that referees miss.
"I know we can't re-referee games but there are real miscarriages of justice."
