Manchester City boss Pep Guardiola would not shy away from naming his best centreback.
The Citizens have put in superb defensive displays in all competition this season, frequently winning games 1-0.
Someone who has made a significant impact on the team is 23-year-old Ruben Dias, who arrived from Benfica in the summer.
Guardiola hailed the defender, and said his other center backs could learn from Dias.
"Yeah, absolutely. Absolutely," said Guardiola when asked if Dias' impact was similar to Virgil Van Dijk's at Liverpool.
"So far, how he's settled immediately, in terms of mentality and he's a guy who lives 24 hours for his profession.
"Every step he does, at home, on or off the pitch, eating, sleeping, recovering time, preparation time, everything is to be perfect during this 95-minute football game.
"That's why. It depends on him to maintain and hopefully we can help him to grow. We are more than satisfied."
He added: "He's not just a player who plays good, he's a player who makes the other guys play good too. It's 90 minutes talking, 90 minutes communicating, 90 minutes leading, 90 minutes saying what they have to do in every single action.
"When that happens, it's difficult for me because he is undroppable. It's quite similar like Eric [Garcia], Eric has this mentality to play 90 minutes talk, lead the other ones.
"Hopefully the other central defenders - John [Stones], Aymer [Laporte], Nathan [Ake] - can learn and not just play for themselves and what they have to do, see what happens close to them.
"That's why it's a football game as a team, not just individuals."
