Has Raheem Sterling met expectations at Manchester City?

With an hour gone of the Capital One Cup final on Sunday and his team leading 1-0 over his former club, Raheem Sterling had a gilt-edged chance to score. Played in by David Silva eight yards out and central to the goal, hitting the target was easier than not. With the ball slightly behind him, he attempted a controlled finish yet contrived to toe it wide. An hour or so later, it counted for little as the penalty shootout won by Manchester City over Liverpool secured his first piece of team silverware in senior football. In that earlier moment we saw an encapsulation of Sterling's career thus far; the potential is clear and impressive, but the execution isn't quite there yet.
