Omar Marmoush, Nico and Abdukodir Khusanov all impressed as we secured an excellent victory that moves us up to fourth in the table.
Marmoush scored a hat-trick in just 14 minutes on a special day for the Egyptian following his move from German side Eintract Frankfurt last month.
Guardiola says the 26-year-old’s movement is extremely dangerous and says he need stay calm after the praise he will receive.
“The highlights are for him, of course,” the City boss said. “Three goals, we knew it – in Germany at Frankfurt he made good numbers.
“Against Leyton Orient he had three clear chances and couldn’t score but we knew sooner or later.
“The dynamic of the group was good and performance was good. He showed what he is.
“Hopefully he can handle the biggest compliments that are coming. It’s non-stop.
It’s so simple, when you play good everyone adapts quickly but when you don’t play good, you need time. It’s not difficult.
“When we played against Chelsea, he played good and we won. He’s a player that we missed, his movements in behind and his pace.
“He likes to attack the space and he helps to play with more time. When we play like we did today, everyone is better – even the manager!”
Nico made his debut at the Etihad Stadium and had a strong performance alongside Ilkay Gundogan and Phil Foden as our midfield took control.
And fellow new signing Khusanov helped City keep a clean sheet as the in-form Alexander Isak was kept largely quiet by our back-line.
“The presence from Nico help us a lot in the 50/50s,” Guardiola added. “He wins seven and we can run. If he loses seven, they would run.
“The club made an incredible investment for the future. He was a player in the Barcelona academy, which is the best in the world to teach you things like body shape.
“[Former Porto boss Sergio] Conceicao helped him a lot to improve being aggressive and smart and how to play different types of game.
“He’s 23, like a mini-Rodri. It’s a big compliment but he has a feeling with that presence. He wins the duels. He’s far away in other things because Rodri is the best.”
On our Uzbekistan defender, he added: “The pace from Khusanov when they make transitions, that’s why we bought him. He’s so fast.
“He’s too aggressive in duels and when you don’t win the ball it’s a transition, but it’s a question of time and he will learn.”
Savinho also continues to thrive following his summer move and the Brazilian winger was influential again in our win over the Magpies.
“The impact from Savinho in his first season in England, with goals and assists, I didn’t expect it,” Guardiola said.
“I knew from Girona he was a top, top player but I didn’t expect the influence he would have in our games.
“Hopefully we can be calm. This season is just to survive but hopefully this game can give us confidence for the season.”
