#3 Sergio Reguilon (Tottenham Hotspur)
Sergio Reguilon has been a revelation for Tottenham Hotspur in the 2020-21 Premier League ever since moving to the club from Spain.
In Spurs' win against Manchester City, the Tottenham backline was an unbreachable wall, and Reguilon was one of the bricks holding it together along with the other members of the back four.
With the North London club becoming a classic Jose Mourinho team reliant on defensive solidity and lightning-quick counter attacks, Reguilon's pace and skills down the left could become even more important as the season progresses.
The Spaniard has already notched up two assists in five appearances this season. As the club chases their first Premier League crown, Reguilon's form down the left channel and his putative partnership with Gareth Bale could be crucial to Spurs' plans.
#2 Andrew Robertson (Liverpool)
Already a Premier League and Champions League winner at the age of 26, Andrew Robertson is not just one of the best left-backs in the EPL but in the world right now.
His partnership with Sadio Mane down the left for Liverpool has already become the stuff of legends and has been instrumental in ensuring the Reds play the kind of devastating football that has helped them win multiple laurels in a relatively short span of time.
In fact, Robertson and Trent-Alexander Arnold on the other flank comprise the most deadly full-back duo the game has seen in years. Their overlapping prowess and ability to go back consitute a vital component in gaffer Jurgen Klopp's strategy.
Robertson has begun the 2020-21 Premier League season in prime form as well, notching up a goal and two assists. He will look to keep contributing as Liverpool continue their quest to defend their Premier League crown.
#1 Ben Chilwell (Chelsea)
Not even Frank Lampard could have imagined the kind of impact Ben Chilwell would have at Chelsea when he was pursuing the then-Leicester City left-back.
Chilwell was always meant for big things. Unsurprisingly, he has been a player who has acted as the touchstone that has revitalised the Blues after an indifferent start to the Premier League campaign; Chelsea have notched up victories on the trot to go second in the 2020-21 Premier League table.
Chilwell's ball-control, crossing and coverage have helped him score two goals and as many assists in just six games this season. and at 23, he could only get better and perhaps become one of the best in the business.
Luke Shaw: He has been consistent enough to start ahead of Manchester United's new recruit Alex Telles.
