Manchester United, Chelsea and Tottenham all won today but incredibly Manchester City lost to newly-promoted Norwich City.
That means that a win for Arsenal tomorrow against Watford at Vicarage Road will take them to third in the standings on the same points as City, who will only occupy second courtesy of goal difference.
Another factor to throw into the mix is that City has played just one top-six side so far in Tottenham, whereas Arsenal has played two, against Liverpool and Spurs.
Obviously it is still too early in the season to be making any predictions or assumptions but beating the Hornets will mean that after five games Arsenal is level with last seasons champions, something no one will have predicted before the season started.
The flip side is that a loss, while not disastrous, would be a significant setback, a draw would not be helpful but it would at least take Arsenal level with Chelsea, Tottenham and United.
The signs are definitely there that this is going to be a season with many twists and turns and that consistency is what will make the difference over 38 games.
City has now joined United, Spurs and Chelsea in shock losses, something that has not befallen Arsenal as of yet and that is a form of consistency, it is understandable dropping points against a top-six side but not against newly-promoted sides or so-called inferior sides on your own ground.
Arsenal can lay down a marker tomorrow and that alone would be a difference from last season.
