No matter who is in the dugout for Rangers and Celtic, there's usually a mutual respect between the men in charge.
But the Old Firm derby being what it is, there's always a bit of needle too. Ange Postecoglou and Michael Beale haven't gone at it hammer and tong on the touchline yet but the signs are there that there's a bit of tension simmering beneath the surface. From the Celtic boss' quip about being more concerned with what he's having for dinner than Beale's appointment, to his Rangers counterpart branding the Parkhead boss "lucky" in a pop at their resources, it's fair to say we're unlikely to see these two sitting down for dinner any time soon.
Writing in his Record Sport column, Barry Ferguson revealed that's exactly how he likes it. He said: "I’m all for a bit of cut and thrust where Beale and Postecoglou are concerned. I’ve seen some people react to it by saying Beale would eat himself if he was chocolate. And I’ve seen others try to claim Postecoglou is in danger of losing the plot because he won’t let the ‘lucky man’ quip lie. But what we really have here is two very clever managers who realise their success depends on bringing the other guy down. That’s not something to be criticised."
