With all the pressure on Manchester City after Arsenal's win just half an hour or so earlier, they succumbed to the stress and dropped two points at West Ham.
But was it the stress or was it simply nothing more than bad luck? Pep Guardiola watched from the stands as his team had 21 shots to the Hammers' solitary effort on goal and even that one was only a millimetre over the line. City had 70% of possession and, on any normal day, that would lead to an easy three points.
Across London, Arsenal would probably have struggled to break down Everton had the Toffees not gone for the three points in the last five minutes. David Moyes set out his team brilliantly, they defended well and even created the better chances on the break.
Had Everton sat back grimly hanging on for the single point, would Arsenal have broken through? Maybe, but very possibly not.
Everton are safe from relegation and had very little to lose, so clearly thought "we might as well have a go". In their first high press committing numbers forward, Arsenal broke and took advantage.
Yes, Mikel Arteta got it right and his substitutions worked a treat. Piero Hincapie got the assist for the first after Max Dowman's superb cross and the other sub, Viktor Gyokeres, tapped it in, before Dowman killed it off minutes later with the second goal.
It was great work from the bench but don't forget that Arsenal did get a little luck and City got none. Then again, you know the old saying – you make your own luck and Arsenal certainly did.
