Scored twice and registered an assist in City's 6-1 thrashing of Southampton on Sunday.
The visitors at least ended their five-game goal drought on the half-hour mark.
Southampton had a couple of half-chances as City eased off late on before Sane wrapped things up in injury-time.
In the opening moments, Aguero drove into the area only to be crowded out by three Saints defenders, before Sterling flashed a risky ball across the face of McCarthy's goal. Sane scored the sixth in stoppage-time, receiving the ball from Sterling on the edge of the area before cutting in and firing an effort past McCarthy to complete the visitor's misery.

Nicki Minaj and Little Mix joined forces for an empowering performance of their collaboration " Woman Like Me ". Shawn Mendes won for best live performer, and British singer-songwriter Dua Lipa was best pop artist .
Palace started the game in brighter fashion.
Defenders Marcos Alonso, David Luiz, Antonio Rudiger and striker Alvaro Morata have not travelled to Belarus. Willian then saw a goal disallowed for offside in the closing stages of the first half.
The Citizens have won eight of their opening 10 matches, drawing the other two, and are out in front by virtue of their superior goal difference compared to Liverpool's.
Morata's omission could be deemed a surprise given he has recently found form, with six goals in seven appearances.
The home side sealed the victory with 20 minutes left on the clock. "He's played three games in a row and sometimes it's better to actually rest than always play".
"We need goals to win".
