David Moyes admitted 'diabolical' goals proved the undoing of his team as they started the Barclays Premier League season with a heavy defeat.
The Gunners lost 6-1 at home to Arsenal - and Moyes pinpointed the visitors' second and third goals as costly.
Robin van Persie's free-kick from the right found defender Thomas Vermaelen beyond the far post and the defender headed back into the bottom corner for a fine debut goal.
Everton's marking for that was dreadful, with Marouane Fellaini and Joseph Yobo seemingly at fault.
But four minutes later when William Gallas headed home another free-kick, this time from Cesc Fabregas, the defending was even worse.
The Frenchman had a free run into the six-yard box to guide his header home completely unmarked. Goalkeeper Tim Howard appealed for cover as colleagues stood motionless.
Moyes said: 'There's real disappointment.
