Manchester City boss Pep Guardiola is happy with what he's seen from Kayky in training.
The 18 year-old summer signing from Fluminense arrived in England last month.
Guardiola told TNT Sports: "He's just arrived. Had some knee problems. He trains with us, gets to know us, gets to know English football.
"He is very young. We know his talent, otherwise he would not have come, or City would not have recruited him.
"He is very smart, very prepared. Fernandinho talks a lot with him, our captains take care of things, that's why Fernandinho is a jewel. Slowly he will be integrated, he will try to get matches in the reserve team, seek rhythm. And soon his achievements will determine what will happen."
