As the old cliché goes: Football is a game of fine margins. It's true. A centimetre can effectively decide a game. It can determine someone's career to its most dramatic extent.
See Saturday afternoon for example. If Raheem Sterling's shot had gone a centimetre wider – or a couple – of Ainsley Maitland-Niles, then Chelsea would have been level with Southampton and would have had the momentum to go on and win the game. There would still be questions over Graham Potter's future, sure, but social media would be a much more pleasant place to be.
But in reality, Sterling didn't score. Chelsea didn't. The Blues remain in 10th place in the Premier League table and have won just one match in 10 in all competitions.
