Arsenal's lead at the top of the table is just four points heading into the final seven matches of the season. Their draw with West Ham on Saturday means it is four dropped points in the same week, the first time they have failed to win in consecutive league games since February.
After moving eight points clear two months ago, that could be as little as one by the time the next round of games is over. It is Southampton next up for Mikel Arteta's men as a chance to respond ahead of Manchester City arises, but the pressure is building.
City have now won their past nine games by a combined score of 34-4. This is what Pep Guardiola's side do and they have started to look like the unstoppable force that many predicted throughout the season. How Arsenal deal with this added weight of challenge in the final run-in may well define just successful it is.
