Arsenal manager Mikel Arteta has been left fuming after his side controversially lost their first Premier League game of the season, and their lead at the top of the standings.
Newcastle claimed a 1-0 win at St James' Park on Saturday through Anthony Gordon's second-half goal that survived a long VAR check for three possible infringements.
Gordon slammed home a finish from close range in the 64th minute after Gunners defender Gabriel failed to clear under pressure from Joelinton.
There was a video review for the ball being out of play in the build up, a possible foul on Gabriel and also offside, leaving the home fans incensed. The goal stood, however, and Newcastle held on in the face of late Arsenal pressure.
"It's embarrassing, it's a disgrace, that's what it is: a disgrace," Arteta told Sky Sports.
"There's so much at stake, we've put in so many hours. I'm here to represent the football club and get my team to compete at the highest level.
"The margins are so small. It's a disgrace, it's embarrassing. That's how I feel and that's how everybody feels in that (dressing) room. You cannot imagine the amount of messages we've had saying 'this cannot continue'. It's embarrassing, I'm sorry, embarrassing.
"You look at the images and I don't know how to feel. I'm wasting my time, we are wasting our time. I don't want to be in the hands of people.
"It's difficult enough to compete against this team - they are a really good team. It's embarrassing, I repeat myself."
