Yes, and I saw this earlier. I last logged on this morning, so, when I get a chance, I'll have a look and see if I can answer your question, BD.
To do this, we dug into every FA Cup and League Cup draw over the past 10 years, including this weekend’s FA Cup fourth-round fixtures, and undertook our own special form of analysis. Ready for the maths?
First, we aimed to uncover the average advantage for all 92 clubs against their drawn opposition. This required factoring in the relative distance in the football pyramid between the two sides, which we measured by the division each club was playing in at the time of being drawn.
We also added an additional category for the “big six” clubs — Arsenal, Chelsea, Manchester United, Manchester City, Liverpool and Tottenham Hotspur.
We then assigned a value to each category, with “big six” sides given the highest value of six, and non-Leaguers the lowest score of one. To factor in home advantage, we also placed an additional .5 score for the home side.
Therefore, our categorisation was: “big six” (value of six points), rest of Premier League (five), Championship (four), League One (three), League Two (two) and non-League (one).
How does that work? For example, Chelsea (six points) are home to Luton (four) on Sunday. Chelsea get an extra half-point for being at home and then we subtract Luton’s score from Chelsea’s and they are then assigned those points. So in this case, Chelsea would be given +2.5pts and Luton -2.5pts. This was then done for every cup draw in the past decade for every team.
For all 92 clubs, we then added their scores from every draw they participated in and divided it by their total number of draws to provide a score of their average advantage against the opposition in cup draws.
