Arsene Wenger praised his Arsenal players for demonstrating a facet of their character that 'people don't know' after victory at Goodison Park on Wednesday evening.
Thomas Vermaelen gave the Gunners the lead after barely seven minutes when he headed in a corner from Robin van Persie, but the visitors were unable to get a foothold in the game.
Everton were hard done by after seeing a legitimate goal ruled out for offside before half-time and responded with a dominant display in the second period.
In order to combat the Toffees' supremacy, the Gunners abandoned their usual free flowing style and continued to frustrate David Moyes' side with some resilient defending.
It was the type of performance onlookers would not expect from Arsenal but was, nonetheless, equally as effective - and Wenger was pleased that his players were able to adapt to the situation.
"We showed a side of us that usually people don't know. It was the only way to get a result tonight," the Arsenal boss told the club's official website.
"It was good to know that we can do that as well. We didn't panic, we did well on crosses which is usually not our strong point. We didn't panic and that is good for us.
He added: "I felt it was a bit psychological - we refused to play because we just wanted to keep the score. Credit to Everton they played very well in the second half."
Three points on Merseyside completed an impressive turnaround from Arsenal as they climbed above north London rivals Tottenham into third place in the Premier League.
