Arsenal recorded just their second Premier League defeat of the season over the weekend, falling 1-0 to Everton at Goodison Park.
The north Londoners struggled to cope with the Toffees press, with the home crowd clearly buoyed on by the arrival of new manager Sean Dyche. Mikel Arteta's side struggled to create many chances before centre-back James Tarkowski eventually broke the deadlock on the hour mark, heading the ball past a helpless Aaron Ramsdale from a corner.
However, the Gunners were frustrated by some refereeing decisions on the day, as replays appeared to show that Everton shouldn't have been awarded the set piece considering the ball came off Alex Iwobi instead of Arsenal man Ben White. Referee David Coote also failed to award the away team a penalty when Arsenal defender Gabriel Magalhaes appeared to be tripped by Everton frontman Neal Maupay.
