West Ham and Cardiff go into Tuesday's League Cup tie locked together in the Premier League, with both teams having won one, drawn two and lost two of their five league matches so far.
In fact, the only difference lies in the goals conceded column, where Cardiff have let in two more than the Hammers - goals that can be traced back to their 2-0 defeat at Upton Park on the opening day of the season.
West Ham's only subsequent win was against League Two Cheltenham in this competition, and they have suffered home defeats to both Stoke and Everton.
The League Cup has been bitter-sweet for Cardiff in recent years. The Welsh club reached the final in 2012, only to suffer the heartbreak of losing to Liverpool in a penalty shoot-out. And they fell at the first hurdle last year, with League Two side Northampton dumping them out.
Cardiff City will be hoping for a role reversal as they prepare to take on West Ham in the Capital One Cup third round on Tuesday.
Malky Mackay's side lost 2-0 at Upton Park on the opening day of the Premier League season after goals from Joe Cole and Kevin Nolan, but the Welsh club have seen an upturn in fortunes since that early setback.
