Celtic legend Frank McAvennie has told The Glasgow Evening Times that Colin Kazim-Richards is not good enough for the Bhoys and fears he could be sent off against Rangers on Sunday.
Hampden Park will play host this weekend as both Glasgow giants battle it out in a Scottish Cup semi-final.
It is only the second Old Firm derby since 2012 and a lot of players on both sides do not have vast experience of the famous fixture and all the hostility with which it entails.
McAvennie knows only too well how an Old Firm clash can affect the inexperienced, having been sent off in his first game versus Rangers after just 14 minutes.
The 56-year-old, however, believes that Kazim-Richards is vulnerable due to his fiery temperament, but does not think the Turkey midfielder is much use in any case.
"I don't think the boy Richards is good enough and he could be trouble. God, he is a live-wire isn't he? He could get sent off at any time,” said McAvennie to the Glasgow Evening Times.
"I've got a great temperament and I got sent off after 14 minutes. He could beat that record.”
Kazim-Richards, a January signing, does seem to have a bit of fire about him; a quality which could serve him well or indeed cost him and Celtic big time on Sunday.
It remains to be seen if manager Ronny Deila will select him, having only started a handful of games since joining the Hoops.
