We may be unlikely to see it addressed directly when Brendan Rodgers and Michael Beale are in the respective dugouts in Glasgow. But the two go back almost 20 years...with Beale previously admitting his new adversary is one of his coaching inspirations.
It's a new challenge facing Brendan Rodgers but there is a familiarity there as the Northern Irishman gets set to take over from Ange Postecoglou. Both because he's been here before, and because he knows the man in the dugout across the city like the back of his hand. Rodgers and Rangers boss Michael Beale go back to the days they were both working within Chelsea's youth system in 2004 and their respective careers have crossed paths various times since; at Liverpool and later in Glasgow while Beale coached under Steven Gerrard.
Rodgers is set to be appointed Celtic's new manager tasked with replacing Ange Postecoglou and maintaining their dominance over Rangers having just stormed to a domestic Treble, something Rodgers was no stranger to during his first term at Parkhead. And Beale is on record admitting he's learned plenty of what he knows from Rodgers' philosophy.
