Birmingham boss Alex McLeish supports Manchester United's Sir Alex Ferguson's demand for appeals to be allowed against yellow cards. Ferguson was livid when Manchester United midfielder Darren Fletcher was booked for diving in Tuesday's Champions League clash with CSKA Moscow.
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."
