He has scored nine goals for City to date, striking five times in his last three outings, all in different competitions.
Negredo went one better than Aguero by netting a hat-trick in the 5-2 Champions League success over CSKA Moscow in midweek and the Argentinian is happy with the combination.
Sergio Aguero: "Yes I am very happy (with my tally) not only for the goals, but for the victories.
"I think most of my goals have helped to win the three points and that's the most important thing for me.
"It's really good, yes.
"Alvaro has arrived this year and played really well and so has the partnership between us. We have to continue on because it is an important part to help the club forward.
"We knew how important the game was and tried to show right from the start that we wanted it over and done with as soon as possible. The most important thing was to reach the knockout rounds.
"To get to the round of 16 was our first objective and we have achieved it.
"(Pellegrini) has a way of making sure his teams play in the way he wants, that we play effective football and that we can challenge for important things. We are in a good place now and we will have to see what happens afterwards."
