Allowing up to 2 assists per goal (which more accurately reflects wingers contributions)

Deeney has played 9770 minutes has scored 33 goals - of which 12 have been penalties - and has 27 assists

Zaha has played 12439 minutes with 25 goals (no penalties) and 50 assists

Of course, Zaha should have several more years of peak production, Deeney not so much.

Zaha is clearly the better (and much more entertaining) player but no doubt several years of Deeney in the Palace team would have been of benefit compared with what we have had
