One of Liverpool's major strengths is their full-backs.

In Trent Alexander-Arnold and Andy Robertson, the Reds possess arguably the two best full-backs in the world at the moment.

But have they been the two best Premier League players in their position this season?

We've taken a look at stats provided by WhoScored.com and ranked every full-back that has played at least 400 minutes in the Premier League this season from worst to best.

61 players have qualified and you can see how they've been ranked below... 

*These stats are correct as of January 18, 2020

61. Emil Krafth - 6.17

60. Neil Taylor - 6.33

59. Yan Valery - 6.36

58. DeAndre Yedlin - 6.41

57. Ryan Bertrand - 6.44

56. Max Aarons - 6.45

Krafth was signed by Newcastle this summer and started five of his side's seven Premier League games to open the season.

However, his performances saw him lose his place in the team and he's played just 50 minutes since.

Valery and Aarons are both young promising full-backs but stats show they've still got a lot to learn.

55. Jamal Lewis - 6.46

54. Ahmed El Mohamady - 6.48

53. Danny Rose - 6.49

52. José Holebas - 6.50

51. Kiko Femenía - 6.50

Rose was once one of the best full-backs in the league but his form has dropped off this season.

Watford pair Holebas and Femenia are also not having the best of campaigns.

50. Sead Kolasinac - 6.53

49. Javier Manquillo - 6.62

48. Séamus Coleman - 6.62

47. Luke Shaw - 6.63

46. Matthew Lowton - 6.65

Coleman has been a great servant to Everton but he's found first team opportunities hard to come by this season after the emergence of Djibril Sidibé.

Shaw's days at Manchester United also look numbered. Brandon Williams has performed well in recent weeks meaning Shaw is no longer first-choice.

45. Erik Pieters - 6.65

44. Adam Smith - 6.66

43. Patrick van Aanholt - 6.67

42. Martín Montoya - 6.67

41. Aaron Cresswell - 6.68

Van Aanholt contributes a lot in attack and he scored a dramatic late winner against Man United at Old Trafford earlier this season.

But his defensive work leaves a lot to be desired, which explains why he's so far down this list.

Cresswell isn't playing at the same level that saw him earn three England caps between 2016-2017.

40. Martin Kelly - 6.69

39. Adam Masina - 6.69

38. Sam Byram - 6.70

37. Joel Ward - 6.72

36. Daryl Janmaat - 6.73

Norwich have talented young full-backs in Aarons and Lewis but it's Byram who has performed the best, according to stats.

Crystal Palace duo Kelly and Ward are having steady but not spectacular seasons.

35. Cédric Soares - 6.74

34. Kyle Walker - 6.74

33. Jonny - 6.75

32. Jack Stacey - 6.75

31. Ashley Young - 6.76*

Walker has lost his place in the England set-up and stats from this season show why that is the case.

*Young has been included in the list despite having recently completed his move to Inter Milan.

30. Ainsley Maitland-Niles - 6.78

29. Angelino - 6.78

28. Benjamin Mendy - 6.79

27. George Baldock - 6.79

26. Ryan Fredericks - 6.80

Maitland-Niles isn't a natural full-back but he's performed admirably in that position for Arsenal.

Mendy's injuries appear to have caught up with him and he isn't the same attacking presence he was towards the start of his Man City career.

25. Arthur Masuaku - 6.81

24. Emerson - 6.81

23. Calum Chambers - 6.86

22. Brandon Williams - 6.86

21. Matt Doherty - 6.86

Chambers could miss the rest of the season after suffering a knee injury, which would be a massive blow for Arsenal.

Statistically, he had been Arsenal's best defender this term.

Williams has been a revelation since making his debut for Man United. The Red Devils have kept clean sheets in six of the last seven games he's featured in.

20. Phil Bardsley - 6.88

19. Jetro Willems - 6.88

18. Reece James - 6.91

17. Enda Stevens - 6.93

16. Matt Targett - 6.93

James has only been on the pitch for 601 minutes this season but he's made his time on the pitch count.

Targett has been the 16th best full-back in the league this season, which may come as a bit of a surprise given Aston Villa are currently in the relegation zone.

15. Dan Burn - 6.94

14. Frederic Guilbert - 6.96

13. Diego Rico - 6.97

12. Oleksandr Zinchenko - 6.98

11. Ben Chilwell - 7.00

Dan Burn is naturally a centre-back but makes it on the list having played the majority of games for Brighton this season at left-back.

Zinchenko started the season as first-choice under Pep Guardiola but has seen his playing time dwindle after Mendy's recovery from injury.

Chilwell has been a key part of a Leicester side that has kept six clean sheets this season.

10. Lucas Digne - 7.08

9. César Azpilicueta - 7.10

8. Aaron Wan-Bissaka - 7.12

7. Joao Cancelo - 7.12

6. Djibril Sidibé - 7.14

Azpilicueta has been one of the best defenders in the league since joining Chelsea in 2012. That's still the case now, despite him now in his 30s.

Eyebrows were raised when Man United spent £50m on Wan-Bissaka last summer. His stats show that was great business.

Cancelo and Sidibe have both performed well since joining Man City and Everton respectively at the beginning of the season.

5. Andy Robertson - 7.19

4. Serge Aurier - 7.23

3. Marcos Alonso - 7.30

2. Trent Alexander-Arnold - 7.42

1. Ricardo Pereira - 7.54

Robertson hasn't been the best left-back in the Premier League this season. That honour, surprisingly, goes to Alonso.

The Spanish defender has only started seven games this season after struggling with injury.

But in that time, Chelsea have kept four clean sheets and he's made four goal contributions (one goal, three assists).

Alexander-Arnold is the best attacking full-back in the world at the moment. He's recorded a ridiculous 10 Premier League assists this term and has helped Liverpool to seven clean sheets.

But his defensive work has come in for question, which could explain why Pereira has been given a higher average rating.

The Leicester defender only has three goal contributions this term but excels in the defensive aspect of the game.
