There have been a number of standout performers in the Premier League so far this season.

Kevin De Bruyne is the early favourite to pick up the PFA Premier League Player of the Year award, having already notched nine assists in the seven games he has played.

Sergio Aguero and Pierre-Emerick Aubamayang have been lethal in front of goal and are also contenders, while Sadio Mane has been Liverpool's standout player in their perfect start.

But who makes up the best Premier League XI so far this season?

WhoScored.com use stats to calculate a overall rating for every player and there are a few surprise inclusions in the best Premier League XI.

Liverpool have been dominant this season but only two of their players make the cut: Joel Matip and Roberto Firmino.

Five players from outside the 'Big Six' also make the side.

GK: Nick Pope - 6.9

RB: Ricardo Pereira - 7.5

CB: Joel Matip - 7.6

CB: Willy Boly - 7.5

LB: Diego Rico - 7.3

RM: Riyad Mahrez - 7.7

CM: Kevin De Bruyne - 8.1

CM: John McGinn - 7.6

LM: Raheem Sterling - 7.8

So that's the best XI, but what about the worst performers in this season's Premier League?

We have decided to omit any player who has played less than 300 minutes this season as it would be unfair to judge a player on such a small sample size.

GK: Ben Foster - 6.07

RB: Emil Krath - 6.15

CB: Craig Dawson - 6.39

CB: Maya Yoshida - 6.4

LB: Ryan Bertrand - 6.27

CM: Morgan Schneiderlin - 6.07

CM: Pablo Fornals - 6.26

AMC: Miguel Almiron - 6.23

RW: Juan Mata - 6.17

LW: Jesse Lingard - 6.26

ST: Glenn Murray - 6.16

It's been a nightmare start to the season for Manchester United. 

They've had trouble in front of goal and two of their attackers, Juan Mata and Jesse Lingard, make the Premier League's worst XI.

It's also been a season to forget so far for the likes of Bertrand, Schneiderlin and Almiron.
