Dean said on the Havertz penalty incident, said: "Watching up in the gantry it looked a stick-on penalty - as did everyone in the stadium.

"But the more you look at it from another angle the defender hasn't made a foul. I can see why the penalty was given but there is no foul. They've rightly come to the correct decision."

Dean: Garnacho's shoulder is offside

It would be the decision to rule out Garnacho's strike that would prove a major turning point.

Casemiro's threaded ball put the Argentine in to coolly strike past Aaron Ramsdale and spark wild celebrations that eventually turned to nerves during a VAR review that ended up in an offside call.

Dean added: "It's obviously very, very tight. At first glance I thought it was offside. There's one or two angles where he looks on and then off.

"When they put the lines up you can't fault the technology - they put the lines in the correct place, they wouldn't have put them in the wrong place. The angles are there to be used and they would have used crosshairs to make sure it's in the right direction.

"His shoulder's offside and that's what they've given. I understand where the manager's coming from because the angle there is not ideal but we've got the technology in the hub to put the lines in the correct position and it looked offside at normal speed.

"Both angles would've been used because there'll be a camera for there and a camera also on the 18-yard line which they would've used.

"Obviously that one there, they've put the lines on and they've come to the correct decision. It did look offside when they freeze-framed it without the lines.

"I'm comfortable with the decision today."

Gary Neville responded: "If we go back to that first angle, it's in line whereas that one obviously has come back the way which means he's not in line."

It was a gut punch for a United side that would soon be left reeling from a knockout blow.

Ten Hag: Sancho not selected on training performances

Ten Hag also revealed that Jadon Sancho was absent from United's matchday squad owing to poor application in training.

"On his performance on training we didn't select him. You have to reach the level every day at Manchester United.

"You can make choices in the front line, so in this game he wasn't selected."

Rice: I knew what today meant and gave it my all

Rice hailed his first Arsenal goal as a "special moment".

The England midfielder told Sky Sports: "Outside looking in, watching Man United-Arsenal over the years, you understand the heritage, you understand these games, the big players and what it means to the fans.

"I knew what today meant and I gave it my all.

"I think first time I controlled it with my chin and scored. But If you don't shoot, you don't score. It was just a special moment.

"It's fine margins that makes these results and in the end we came through with the result."

Arsenal manager Mikel Arteta praised match-winner Rice for his overall performance.

Arteta told Sky Sports: "He (Rice) was outstanding but the whole team as well. He imposed himself on many occasions and he gave us the momentum the team needed.

"It was beautiful to celebrate it at the end with our fans with the way it happened.

"At this level it is about small margins. I think we had to win the game but it could have gone the other way if they had scored for 1-2. That will to win is beautiful."
