Fernandinho is edging closer to signing a new deal with Premier League champions Manchester City.
The 34-year-old, who is out of contract at the end of this campaign, has revealed he will be extending his stay at the Etihad stadium.
"When I renewed at the end of 2018, we put a clause that if I reached certain goals, my contract would be renewed automatically," the player told ESPN Brasil.
"Conversations have already started, we talked about it last month. I am close to reaching those goals and renewing the contract, but we can only confirm it after signing."
The Brazilian, who joined the Citizens from Shakhtar Donetsk back in 2013, also said he is happy to help Pep Guardiola's side at the back where they have been suffering from injuries.
"It's good as long as you can be at the highest level," he said. "Playing in a different position opens up the range of learning.
"In defence, I see the game in a different way. It has been very cool and the guidance I have received from Pep has been very good.
"At 34, playing in the Premier League is a source of pride. Many, many players wanted to be experiencing what I am experiencing."
