The Brazil attacker, after pushing to join Tottenham over the summer, is now set to sign a new contract offered by City to 2031.
The Daily Mail says City chiefs hope to see Savinho secured to his new deal next week.
City manager Pep Guardiola said of his young winger on Friday: "Always for the people up front it is about numbers, goals and assists.
"Savinho created a lot last season but in the final third, the final moment he was a little bit too hectic.
"But the moment he learns that, because he is so young, the more he improves, he'll be a top-class player because he can play on both sides, he's got the speed and the work ethic.
"Savinho will make this step, naturally it will come and he will be a top player for Man City."
