KVV is a striker. Strikers have to have good balls played to them in scoring positions.  KVV, Efford and Shields are playing this new '2 in midfield'  formation that the manager has come up with on the half way line. In fact, today Efford spend a while clearing up in the left back position (like Tony Watt did early in the season). It doesn't matter if you have the best striker in the world playing for you. If you only ever punt the ball over his head or give him the ball on the half way line, he's not going to score.
