With Sterling, it's undeniable that his form has deteriorated dramatically in just a few months (think in contrast how well he played against Lampard's Chelsea in January) but I have come to believe that some of the criticism of him is rooted in racism. Why? It's in large part because he is persistently accused of being lazy, which is a classic racist trope directed at blacks. As I have said repeatedly on forums in addition to this one, Sterling is capable of instant control, sublime dribbling skills and terrific shooting, and at the same time of appalling inability to control the ball, hopeless attempts to dribble past players, and incredible misses when presented with simple chances in front of goal. The word for that is inconsistency: laziness has nothing to do with it, and as any honest observer would admit Sterling tries if anything too hard to make up for his failings during the course of a match.
