City played as Pellegrini had promised when he arrived in the summer but after the dip in form that followed the Newcastle display, the Chilean knows the challenge is to maintain such standards.
Pellegrini said: "It is the way we want to play. We played very similar to how we played the first game against Newcastle.
"After that game, for different reasons, (we found) it is not easy to play (like that) with the regularity I want to do it.
"I think that is normal in this period of the season, we are working and playing a different way.
"But the most important thing is the players trust in what we are doing. We demonstrated that during 90 minutes.
"We are just starting. Every match is different but all the fans can be sure we will try to play with the most offensive and attacking team we can.
"Also to be an attacking team you must work on defending and I think we defended really well."
