Territoriality, testosterone and Tottenham: home advantage in football
Wednesday, January 31st, 2007A few hundred yards away around 40,000 people are singing - well, yelling - “Stand up if you hate Tottenham”. The noise of the home support at the Emirates Stadium is loud enough from where I’m sitting - it must be cacophonous for the players on the pitch. I can’t imagine what the noise must have been like when Arsenal’s support didn’t consist mostly of metrosexual graphic designers.
Anyway, my question is, does the psychological impact of such unrelenting hostility from such a large crowd of people help account for the puzzling phenomenon of home advantage in football? For an imperfect (given the season’s only part over) illustration of this, have a gander at this chart I made out of the current Premiership table.

Clearly playing at home makes a huge difference to most teams. Liverpool’s home form is the best in the league, but away they’re worse than Bolton. Tottenham have the fifth best home form and the fourth worst away form. Really bad away form will probably get you relegated: the bottom three get more than three points at home for every one away. And consistency home or away will push you towards the top, (unless you’re Wigan, equally shit at home or away): Man Yoo and Chelsea are both nearly as good away as they are at home.
So what’s going on? (By the way, Arsenal have just scored - at this stage I’m able to tell by the volume of the roar). It’s possible that home advantage as such doesn’t really exist, but the belief that it does makes away teams play defensively and thus lose more often (or win less often). But assuming that the effect is somehow more ‘real’ than that, is it down to player psychology, crowd effects, physical fatigue from travel, referee bias, or what? A quick literature review (thank you, Google Scholar) throws up the following findings:
- Home Ground Advantage of Individual Clubs in English Soccer. Stephen R. Clarke, John M. Norman (1995) “… A paired home advantage is defined and shown to be linearly related to the distance between club grounds”.
- Home Advantage in Sport: An Overview of Studies on the Advantage of Playing at Home. Nevill A.M.; Holder R.L. (1999) “A number of studies provide strong evidence that home advantage increases with crowd size, until the crowd reaches a certain size or consistency (a more balanced number of home and away supporters), after which a peak in home advantage is observed. Two possible mechanisms were proposed to explain these observations: either (i) the crowd is able to raise the performance of the home competitors relative to the away competitors; or (ii) the crowd is able to influence the officials to subconsciously favour the home team. The literature supports the latter to be the most important and dominant explanation.”
- And my personal favourite: Testosterone, territoriality, and the ‘home advantage’. Neave N, Wolfson S. (2003) “In an initial study, we showed that salivary testosterone levels in soccer players were significantly higher before a home game than an away game.In a second study involving a different group of soccer players, this finding was replicated over two home games, two away games, and three training sessions. Perceived rivalry of the opposing team was important as testosterone levels were higher before playing an ‘extreme’ rival than a ‘moderate’ rival. Self-reported measures of mood in both studies were not linked to testosterone level. The present results corroborate and extend earlier findings on the relationships between testosterone, territoriality, and dominance in human competitive encounters and further suggest an important role for testosterone in the home advantage seen in various team sports”.
