To all intents and purposes, Cardiff City and Swansea City are teams with broadly similar capabilities.
Since Cardiff's drop back down into the Championship in 2019, both clubs have followed comparable trends. They both challenged for the play-offs, armed with parachute payments from their stints in the top flight, before dropping into mid-table and, at times, a little further down that ladder.
Swansea are an extremely well-organised side who play eye-catching, pleasing football, but they are not infallible, although Cardiff always make them out to be.
