ALLY MCCOIST sent a "be scared" warning to Alan Brazil this morning as the pair continued talkSPORT's build-up to Sunday's Rangers vs Celtic match.

Glasgow's big two go head to head this weekend with Ange Postecoglou's Hoops currently three points clear at the top of the Premiership.

Speaking ahead of the match, McCoist said this morning: "Okay Al, mate. It's that time of the week, that time of the month, that time of the year again, pal.

"The difference is, my son, this game is at Ibrox. The home of the champions.

"I accept we weren't at our best when we played at your place, however, you're travelling across the city to the home of the champions.

"Be scared, Al. Be very, very scared."

Brazil then responded: "Do you know something, it's amazing how he changes in 24 hours. I was sitting having a glass with him yesterday.

"He's like that, 'we're playing rubbish at the moment, I fancy Celtic to beat us'.

"How can he come on, live on air and say that?

"My hope is, nothing to lose, don't sit back, go for it like they did right from the whistle at Parkhead. Went for Rangers' throats, I would do it again.

"Rangers are not playing that great. In Europe, yeah, but in the SPL, no.

"So Celtic have got to go for it."
