You don't actually achieve anything by reaching the top of the table at the start of October - it's at the start of May that you really want to be there. If Cardiff can get the better of Birmingham, though, they will write themselves into the record books, equalling their best ever run of home wins at the beginning of the season.
It was back in 1946/47, when league football resumed after the Second World War, that the Bluebirds last won their first five home games. It certainly won't be easy to match that this evening - the Brummies arrive fresh from a 1-0 victory at Brighton on Saturday, when former City favourite Chris Burke struck a spectacular winner.
Cardiff will be without Tommy Smith, sidelined by a groin strain, and their supporters will hope that Craig Bellamy, so impressive in the weekend win against Blackpool, is fit enough to play two games in four days. They will also hope Peter Whittingham continues to display the sort of form which makes a good case for claims that he may just be the best player outside the Premier League.
Even if the Bluebirds do pick up the three points, of course, it may not be enough to take them to the top - with Brighton at home to struggling Ipswich, you'd fancy the Seagulls to rediscover their winning ways. And Wolves could also edge above City by piling in a few goals against Palace.
Matching that 66-year-old winning run, though, could be taken as a very optimistic omen.
That 46/47 team, mostly made up of local talent and managed by Billy McCandless, went on to win the old Third Division South and secure promotion. So.....
