Negredo, signed from Sevilla for £20million this summer, has made a positive impression at City, having a goal disallowed against Newcastle, finding the target at Cardiff and then adding his latest effort against Hull.
Pellegrini said: "I expect from Alvaro Negredo exactly what we are seeing every time he plays.
"I know how good a striker he is. With Alvaro and Edin (Dzeko) we have two very good strikers and we need both of them."
