I missed the poll - but would have voted for Sane. His offensive threat is awesome - and - he's completely bought into Pep's system, running full sprint back on defense on several occasions - winning the ball back at least once or twice.
And, when he beats his man on offense, a tremendous cross/shot on goal nearly always follows. One of his crosses came in at pace, traveling about a yard in front of Chelsea's goal - a sure tap in, deserving of an assist.
This year, Sane has come on in leaps and bounds.
