Liverpool and Manchester City remain the pacesetters with victories, the latter emphatically thrashing Watford 8-0.
But elsewhere everyone else are both capable of impressive wins and humbling defeats with Norwich losing to Burnley having just beaten title holders City.
Tottenham Hotspur and Manchester United have been left on the verge of crisis as they lost to top six targeting Leicester City and West Ham United, respectively.
Arsenal, meanwhile, somehow came away unscathed against Aston Villa despite playing the second half with 10 men after Ainsley Maitland-Niles’ red card.
Some wins have been deserved this season but on other occasions clubs look like they have been a little bit lucky with the results falling their way.
Liverpool, according to ‘expected goals’ (xG), could have lost to Chelsea with data suggesting the shot quality was worth a 1.71-1.10 win for the Blues.
To get a better look at how sides are doing, the xG metric allows us to get a better picture of just how teams are performing.
What is expected goals?
- Expected goals (xG) is a statistic used to work out how many goals should be scored in a match.
- Every single shot is awarded an xG value based on the difficulty of the attempt, with factors including distance from goal, type of shot and number of defenders present affecting the value.
- The higher the xG of a particular shot, the more likely a goal should be scored from that shot.
- The xG value of every shot in a game is then used to calculate the expected goals in a particular match.
