I ain't going to defend any Everton player who is either crap or not putting in the effort, but I can't see the 4 or 5 "great chances" DCL is supposed to have not taken.
64 minutes-weak curler from right side past few defenders=half chance.
72 minutes-Richalison headed down hard, hit DCL ankle, ball popped up, got away snap shot, keeper right on top of him=half chance.
80 min-Richarlison firm low cross, DCL got across defender from miles back, failed to make significant contact at speed=half chance.
90+2 min- The only one he really should have buried in my opinion, free header.
If every centre forward scores every time the comentator/pundit exclaims"he has to score there" they'd all be on 30+ a season.
