Far too often Sterling takes too many 'small' touches, extra half steps and just overall too long to set himself to take the shot on often leading to it being blocked or him not taking it on at all in the end.
He's clearly lacking in the first time shooting department with Kev and Sergio obviously being the best at it by some distance.
For the number of pens, Aguero has scored he doesn't really fill you with confidence either tbh, he seems to be getting worse at them imo, Tevez was another, all a bit hit and hope.
Yaya and Mario, cool as you like and you never felt they would ever miss.
