The players who created the goals for Everton this season (aka "assists")
are defined variously as:-
The penultimate Everton player touching the ball in a move which leads to a goal;
The Everton player fouled in the course of winning a converted penalty or direct free-kick;
The goalscorer himself where the goal results from a solo effort not involving any other Everton players.
Credit for Everton goals scored primarily from an error by an opposition player is given to the last Everton player involved in the build-up or to Everton player who helped to force that error.
