The Brazilian, who will mark his fifth year at the Club in June, has become an integral part of City's squad.
His tireless workrate and ability to regain possession are pivotal traits in this record-breaking Blues side, allowing the attacking players to concentrate on their offensive duties.
Fernandinho credited his displays to Guardiola, who also occupied the defensive midfield role in his playing days.
“I think this is my best season so far,” he told CityTV.
“The consistency I have had this season for me is very important. I try to play at same level every game.
“Pep Guardiola played in the same position as me. He knows very well the right way.
“You could see it last season when he joined us. He helped me to improve a lot, especially talking about small details to improve myself.
“This helped me a lot and I am enjoying being part of this team and working under him.”
