The sending-off of Newcastle striker Aleksandar Mitrovic as early as the 16th minute was key in deciding the outcome of the match.
Newcastle fans were not pleased with the decision and made their feelings clear throughout the game.
Arsenal legend Wright was not impressed with the behaviour of the Newcastle supporters and criticised them severely in The Sun.
“I was at the Newcastle v Arsenal match at the weekend, in the middle of the Toon fans, and was disgusted by the abuse they hurled at Andre Marriner,” Wright wrote in The Sun.
“It wasn’t just a small group — it was thousands of them acting in unison — and I found it unfair and deeply offensive.
“Ref Marriner got the decision to send off Aleksandar Mitrovic absolutely spot on. He went in over the top on Francis Coquelin with his studs showing and it was an automatic red card.”
“I don’t like to see bullying in any form, and that is what the Toon fans were doing,” added the former Arsenal star. “It’s not on, and when it gets this bad the football authorities have to look at it and take action.”
An own goal from defender Fabricio Coloccini in the 52nd minute proved to be the difference between Newcastle and Arsenal at St. James’ Park last weekend.
Over the course of the 90 minutes, hosts Newcastle had just 26% of the possession, took one shot which was not on target, and earned no corners.
Visiting Arsenal had 74% of the possession, took 22 shots of which nine were on target, and earned nine corners.
