Glad to see Sterling get the extension.
Sterling's game has grown by leaps and bounds under Pep - he's one of our best players now, contributing with assists and goals as well as on defense.
Still, there's potential for improvement. Namely, Sterling is still far too reluctant to shoot - if a pass seems to be on, he'll more often than not attempt the pass - even when a shot on goal is the better option.
Too, Sterling seems to be a bit clumsy at times - inexplicably so (e.g., his recent kicking of the turf and subsequent tripping).

TL/DR - Sterling is class. But still suffers from a bit of rawness in his game and lack of confidence. Under Pep, he may get better still.
