The 25-year-old attacking midfielder joined City from Wolves in the summer and has clocked up 17 appearances for the Blues to date.
He arguably had his best game for the Club yet against Burnley, assisting Julian Alvarez’s opening goal and causing the Clarets’ defence problems throughout.
Asked at his Friday press conference whether he thought Nunes was really starting to settle in, Guardiola replied: “Absolutely. It takes time for a player when they arrive to settle with every member of the team or be in love with a guy like Matheus.
“Everyone is delighted to have him in the locker room; he has a specific quality that we didn’t have [before]. His transition play is one of the best I ever seen.
“The way we play and the dynamic, sometimes we need a little bit longer, but for specific things, he is fantastic.
“We were really pleased with his performance; the first goal [against Burnley] was fantastic.
“The more moments he can get with Erling, Phil, Julian, Jack and Jeremy, the beter. He makes these movements like Kevin.
“He is young and we are delighted.”
