English football · Leeds (Premier League) and Millwall (Championship)
A rivalry with no geography in it, between two clubs whose supporters have been hostile to each other since the 1970s; the police treat it like a local derby.
The two clubs are in different divisions, so the rivalry is not on this season’s league fixture list. When they are back in the same division, its games carry the rivalry in the Couchcall score again and this page moves to that league.
