The victory was only City's fifth in 16 games and was their first at home in the Premier League for almost three months.
"Obviously we are all behind him (Guardiola) and follow what he says. The best is yet to come.
"The last few results have also been because we played against other teams who were also very good. It's always tough, and always depends as much on the other team you play."
Nolito added: "You always need to win after several games where you didn't get the three points at home. It was difficult, but it was important to get the three points and now we think of Arsenal.
"It will be a hard game but I guess Arsenal will come and try to get the three points, as that is their philosophy of football. It is also ours, so we will have to see who gets the points. It's difficult because they are rivals in the title race."
