Celtic’s coronation shows Scotland needs end to 40 years of title tedium | Ewan Murray

When Callum McGregor lifts the Premiership trophy on Saturday, it will be four decades since a team other than Celtic or Rangers won the top flightThis Scottish football season involved a debate surrounding the possibility of reconstruction. Would 10, 14 or 16 be the ideal number of Premiership sides, as opposed to the present dozen? There was, however, a tartan elephant in the room. Scotland has been operating a one, one-and-a-half or two-team league for far longer than is healthy. There is no indication that can change.

Cliche suggests Celtic and Rangers joust for honours, and occasionally they do. This, however, is an unprecedented spell of Celtic dominance.
