David Moyes felt the 4-1 scoreline was not an accurate reflection of Everton's performance against Arsenal.
The Toffees slipped to a heavy home defeat, despite taking a first-half lead through Tim Cahill.
Arsenal scored four times in the second period, while both sides had a player sent off in a heated climax to the contest.
Moyes believes Everton deserved to emerge victorious, with the Goodison boss perplexed by the result.
"I could not see that coming at half-time - I couldn't really see it coming well into the second-half either," said Moyes.
Not usual Arsenal
"Overall I felt we were the better team, the best team lost. I felt we deserved to win the game and played the best football.
"We passed it better than Arsenal and they scored with humps up the pitch, didn't they?
"It was route-one Arsenal, we couldn't deal with it, and it was not Arsenal-type goals.
"For all the stuff talked about the way they play, it was not their usual type of goals that beat us.
"We cannot hide that we made mistakes for the goals, but I will take some convincing that Arsenal were better than us.
"The scoreline was not a true reflection. I felt that we were always in with a chance of getting it back."
