Arteta told Arsenal players they had been 'impressive' in defeat at Newcastle

Mikel Arteta reportedly praised his players in the dressing room and detailed the reasons he believes Newcastle's winning goal should have been disallowed before railing against the 'embarrassing' officiating in his post-match comments to the media.

The Gunners saw their unbeaten start to the Premier League campaign end at St James' Park thanks to Anthony Gordon's contentious second-half strike.

Doubts over whether the ball had gone out of play, a potential foul on Gabriel and a possible offside were all checked and ultimately cleared by VAR, handing the Magpies the win and enraging the visitors.

According to The Mirror, Arteta used the opportunity to cultivate a siege mentality among his group and credited his players with a putting in a display worthy of a point.

The outlet also claim the Arsenal boss got one of the club's video analysts to replay Gordon's winner while he outlined why it should not have been allowed to stand.

The Spaniard then emerged from his bunker to address the media. Incandescent with rage he slammed VAR and braded the decision 'embarrassing' before the club backed him up in a statement on Sunday.

'The Premier League is the best league in the world with the best players, coaches and supporters, all of whom deserve better.' The statement read.

'PGMOL urgently needs to address the standard of officiating and focus on action which moves us all on from retrospective analysis, attempted explanations and apologies.'

Arteta's comments have added to the growing scrutiny around VAR this season.

The most controversial VAR decision of the season came when Luis Diaz's had a goal incorrectly disallowed during Liverpool's 2-1 defeat by Tottenham in September.

Wolves manager Gary O'Neil has been vocal in his criticism
