Russell Martin believes Cardiff City's managerial merry-go-round has helped his Swansea City side become so dominant in the South Wales derby in recent years.
Since the Bluebirds returned to the Championship, they have now had five managers in the dugout in seven derby fixtures. The Swans, meanwhile, have had only two in Steve Cooper and Martin.
In a fixture which has been famously tightly-fought for more than a century, Swansea have had the wood over their rivals in recent times. Martin, in fact, doesn't even know what it's like to be on the losing side, despite taking charge of three derby fixtures.
