Cardiff City had one Premier League season in these nine: 2013/14. The other eight were spent outside the Premier League.
It began with the result the rebuild removes. On 25 August Cardiff beat City 3–2 in their first top-flight home game for 51 years: their first Premier League win. Take City out and that win goes, and three points with it. The 4–2 defeat at City in January had earned nothing, so it changes nothing.
30 becomes 27. For real Cardiff finished 20th. Without City they are 19th of 19: last either way, seven points from safety. The one place gained is City’s, and it is the free place and no more. Norwich, Fulham and Cardiff still go down.
So the rebuilt table keeps the season’s ending and takes away the afternoon that opened it.
