For the second successive game at the Emirates Stadium, Arsenal played in front of vast swathes of empty red seats on Sunday.
Arsenal blamed heavy snow for the low attendance in their recent defeat against Manchester City, but the no-show against Watford could only be put down to a fatal combination of anger and apathy after another miserable season.
"Must be -4 and snowing again at the Emirates," Manchester United legend Gary Neville, now a prominent pundit, tweeted soon after kick-off.
"There is a lot of negativity. It is like rain in England, it is easy to get," he said.

"Of course I worry because I want our fans to be behind the team, but after what happened in that week it is understandable.
"We want to have the fans on our side and we do everything to make that happen.

"We suffered a bit at the start of the second half but after that with our spirit, we stuck together and in the end it was a convincing win," he said.
"It gets us out of this negative spiral a little bit. We had a nightmare week. There is still some work to do, but overall we are in a good way."
Deeney had questioned Arsenal's spirit after Watford beat them in October and Wenger said a desire to prove the striker wrong had motivated their performance.
"Cech had to wait a while to save a penalty. It's quite fortunate that it's against Deeney," he said.
Watford boss Javi Gracia refused to blame the defeat on Deeney's jibes, which came before he was in charge.
"Troy was concentrated on playing well and helping the team," Gracia said.
"I don't know what Arsenal were thinking, but I'm happy with him.
"I'm responsible for my words. I respect all the teams, Arsenal as well.
