Football is increasingly a game of numbers. Clubs now have almost as many statisticians as they do fitness coaches. Every game, each player's performance is categorised in the minutest detail. The number of yards run. The number of passes made and passes completed. The number of tackles made. The list is endless.
Yet it sometimes feels the more data that becomes available, the harder it is to work out what it all exactly means.
Start with the basics. Tottenham's 33 points gained from 17 matches played must represent a good start to the season. When you consider the financial resources at Spurs compared to the four teams above them, they must surely have over-performed to be just four points off second place.
