A few months have come and gone this season and Liverpool currently lead the Premier League after eight games.

But while Liverpool are flying, the likes of Watford have had a dismal start to the season.

Javi Gracia has already lost his job while his replacement, Quique Sánchez Flores, has so far failed to turns things around.

They are yet to taste victory in the league this season and are two points behind Newcastle, who have their fair share of problems themselves.

While there have been a number of good performers in the league this season, there have also been a lot of players that have flattered to deceive.

We recently used stats from WhoScored.com to determine every Premier League club's best player so far this season.

And now we are doing the same to list every Premier League club's worst player so far this season.

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.

Arsenal: Sead Kolasinac - 6.51

Kolasinac's place in the side is in serious jeopardy now that Kieran Tierney is back from injury.

Aston Villa: Tom Heaton - 6.29

Villa's summer signing has conceded 12 goals in eight games so far this season.

Bournemouth: Adam Smith - 6.37

Bournemouth have conceded seven goals in the four games Smith has featured in.

Brighton & Hove Albion: Glenn Murray - 6.16

No goals in seven games so far this season.

Burnley: Chris Wood - 6.55

Wood has scored three goals in his last three games but struggled badly to open the season.

Chelsea: Kepa Arrizabalaga - 6.32

Kepa is part of a Chelsea defence that is the joint third worst in the league. Kurt Zouma hasn't been much better.

Crystal Palace: Patrick van Aanholt - 6.68

Crystal Palace's players are rated highly across the board. Van Aanholt has scored winners against Man United and West Ham but has the lowest rating at the club.

Everton: Morgan Schneiderlin - 6.07

Schneiderlin was one of the best midfielders in the Premier League at Southampton. Statistically, he's now one of the worst.

Leicester City: Hamza Choudhury - 6.37

Choudhury started the first three games but has since been deployed off the bench by Brendan Rodgers.

Liverpool: Adrián - 6.41

Adrian has only kept two clean sheets since coming into the side. He made a disastrous mistake against Southampton.

Manchester City: Ilkay Gündogan - 6.46 

Gundogan hasn't exactly been bad. Just not as good as his teammates.

Manchester United: Jesse Lingard - 6.26

Lingard is still yet to score or record an assist for his side in 2019.

Newcastle United: Emil Krafth - 6.18

It's fair to say the summer signing has not enjoyed his start to life in English football.

Norwich City: Max Aarons - 6.27

Aarons has been a permanent fixture in the worst defence in the Premier League.

Sheffield United: Callum Robinson - 6.37

Robinson has scored just once for his side so far this season.

Southampton: Ryan Bertrand - 6.33

Now 30, it seems Bertrand's best days are behind him. Che Adams has only been marginally better.

Tottenham Hotspur: Moussa Sissoko - 6.64

Sissoko has made just one goal contribution so far this season.

Watford: Ben Foster - 6.08

It could have been anyone. Foster has already been beaten 20 times in the league this season.

West Ham United: Pablo Fornals - 6.26

It's been a slow start for West Ham's summer signing.

Wolverhampton Wanderers: Romain Saïss - 6.38

Saiss takes bottom spot, with Conor Coady and Leander Dendoncker not far behind.
