Arsenal were haunted by their dismal away form yet again as Phil Jagielka gave Everton a 1-0 victory that dented the Gunners' Premier League top-four bid on Sunday.
Jagielka was only drafted into Everton's starting line-up at the last minute due to an illness to Michael Keane.
The Everton defender made the most of his call-up with the game's only goal in the early stages at Goodison Park.
It was another away-day flop for Arsenal, who maintained their wretched record as the only club in the top four divisions of English football not to have kept a clean sheet on their travels this season.
Unai Emery's side remain fourth in the Premier League, but they are ahead of fifth-placed Chelsea only on goal difference as the race to qualify for the Champions League heats up.
Everton had threatened from one of Lucas Digne's long throw-ins before the full-back delivered the set-piece that led to Jagielka's opening goal on 10 minutes.
His throw was flicked on by Jagielka, for Dominic Calvert-Lewin to attempt a header on goal that led to the ball taking a kindly bounce and falling to Jagielka again.
