Some of the best players in world football play in the English top-flight.The quality of the Premier League is excellent. While the likes of Cristiano Ronaldo, Mohamed Salah and Kevin De Bruyne tend to grab the attention, some world-class defenders play in the Premier League as well.On that note, let's look at the five best centre-back duos in the Premier League right now (2021).#5 Adam Webster - Lewis Dunk (Brighton & Hove Albion)Leeds United v Brighton & Hove Albion - Premier LeagueAn all-English centre-back partnership kicks off our list. Adam Webster and Lewis Dunk have both established themselves as two of the better centre-backs in the Premier League.Brighton & Hove Albion have impressed under the management of Graham Potter. Dunk and Webster, in particular, have shone. Dunk is a product of the Brighton & Hove Albion academy and the captain of the club. Physically dominant and renowned for his personality, the England international has led the club well.Adam Webster@AdamWebster31Delighted to have signed a contract extension at this great club @OfficialBHAFC!Since the day I came in everyone has been incredible with me & I'm excited for us to build on what we’ve achieved together so far.Can't wait to have you all back with us at the Amex this year! 🙌🏻5:47 AM · Aug 2, 2021125435Delighted to have signed a contract extension at this great club @OfficialBHAFC!Since the day I came in everyone has been incredible with me & I'm excited for us to build on what we’ve achieved together so far.Can't wait to have you all back with us at the Amex this year! 🙌🏻 https://t.co/8O9u18W3lWWebster, on the other hand, is a ball-playing centre-back. The 26-year old did not come cheap, costing the Seagulls £20 million in 2019. Webster has not disappointed and it would not be surprising to see him become an England international soon.Shane Duffy has made an excellent start to the 2021/22 campaign as well. Brighton & Hove Albion sold star centre-back Ben White went to Arsenal this summer for nearly £53 million. They did not buy a replacement, but given the form of Dunk, Webster and Duffy, this decision seems understandable.#4 Ruben Dias - Nathan Ake (Manchester City)Manchester City v Leicester City - The FA Community ShieldManchester City manager Pep Guardiola has an abundance of options at centre-back. It is not easy to predict which pairing he is going to go with for the next game.One certainty is Ruben Dias. The Portugal international joined Manchester City from Benfica for £61.2 million last summer. His performances since then have seen him labeled as one of the best centre-backs in world football. His impact last season was such that he won the Premier League Player of the Season.B/R Football@brfootballRuben Dias receives his Champions League Defender of the Year award 🧱12:30 PM · Sep 16, 202111996656Ruben Dias receives his Champions League Defender of the Year award 🧱 https://t.co/1g07uv4rmDJohn Stones partnered Dias last season, to excellent effect. This time around, Guardiola has alternated between Aymeric Laporte and Nathan Ake. Both Ake and Laporte are left-footed centre-backs, and both of them cost a lot of money.Ake joined the club from Bournemouth last summer for nearly £41 million. The Netherlands international was not a consistent presence in Manchester City's backline last season. This time around, he has made a strong start to the campaign and the 26-year old looks set to provide strong competition to Laporte and Stones.Also Read: 4 managers who could replace Ole Gunnar Solskjaer at Manchester United
