Newcastle United handed Arsenal their first Premier League defeat of the season with a 1-0 win on Saturday thanks to a controversial second-half goal by Anthony Gordon after a long VAR review that left visiting manager Mikel Arteta livid.
Gordon scored in the 64th minute, firing past goalkeeper David Raya from close range after a goalmouth scramble.
There was a VAR break of four minutes six seconds to check if the ball went out of bounds, whether there was a foul in the build-up and for offside before the home fans could celebrate.
Newcastle, who are unbeaten in their last seven league outings, climbed to sixth on 20 points after 11 games. Arsenal, who failed to score for the first time in all competitions this term, are third with 24, three behind leaders Manchester City.
The victory capped a brilliant week for Newcastle, who humbled League Cup holders Manchester United 3-0 in their fourth round clash at Old Trafford on Wednesday.
Arteta was been intent on turning the tide after a disappointing few days that saw his side eliminated from the League Cup with a 3-1 loss at West Ham United
