Manchester City boss Pep Guardiola has hailed the impact of Ruben Dias this season.

The 23-year-old has enjoyed a fine start to life in England since his summer arrival from Benfica, bolstering a City side which currently boasts the best defensive record in the Premier League.

Guardiola said, “[His impact] has been massive.

“Not just with John (Stones). When playing alongside Aymer [Laporte], Eric [Garcia] or Nathan [Ake], he is a guy who has the ability to live every single action during 95 minutes.

“He is always concentrated, doing what he has to do and helping his mates - holding midfielders, full-backs and central defenders - always be concentrated.

“That is not easy to find in a 23-year-old.

“We knew the quality on the pitch. We knew the personality he had, but of course we are impressed with the mentality and the physicality to play every three games.

“Always you expect the best, but we are more than delighted with his behaviour and what he provides for the team."
