Watford's passion and determination showed exactly what was missing at Arsenal in the second half – John Cross

In one way or another, they managed to throw it away in the most imaginable way from Arsenal.

At two goals of the race, Arsenal pressed the self-destruct button with a mixture of kamikaze defense and pure stupidity.

Will they learn one day? Well, you start wondering if Unai Emery can teach them or if the same old problems are so deeply embedded in the Arsenal constitution that fans will have to wait for a new generation to appear.

At the final whistle, Pierre-Emerick Aubameyang dragged himself to the end, shaking his head in despair and probably wondering how he could score twice without winning.

The answer was obvious as Watford's new boss, Quique Sanchez Flores, inspired a second half full of passion and determination, which was exactly the opposite of Arsenal's abominable surrender.

This will surely be one of the worst 45 minutes of a team you'll see in the Premier League this season versus fighting, scrapping and fighting in Watford and, in the end, it really should have won.

No wonder roving fans booed their team off the field. In contrast, Watford had created an atmosphere that, according to Flores, will change the mood of their season.

Incredibly, Arsenal faced 31 shots, its highest since the start of Opta's statistics in 2003/04. With such a weak defense, it was obvious that they would score goals.

We are already losing the number of goals David Luiz has given up since his arrival when he conceded a foolish penalty and Arsenal has constantly bet on the other side to cost him the other goal.

Some Arsenal players wandered in the second half, without urgency or determination. Jogging after giving up the ball as substitute Joe Willock did is no more acceptable than Granit Xhaka's lost passes or Matteo Guendouzi's total fumble.

Emery should also take his share of responsibility also because his replacements were terrible. His decision to pull off the excellent Dani Ceballos was booed while letting Nicolas Pepe play for the 90 minutes was odd given the fact that he had contributed so little and that the match had gone over. .

Watford would have been unlucky enough to be 2-0 at half-time, but Aubameyang made the difference between the two teams with his clinical finish.

Aubameyang's first goal came after 22 minutes when Ceballos won a tackle against Will Hughes. Sead Kolasinac led an attack forward and made a perfect pass. Aubameyang's turn was wonderfully simple and gave him the space to throw the ball into the goal.

Ten minutes later, Arsenal scored a goal that showed what they were capable of when they thought about it, a great move with 20 assists in preparation, before Aubameyang scored again with his 14th goal in his last 14 games .

The slow, patient patient accumulation accelerated when Xhaka found Mesut Ozil and let Ainsley Maitland-Niles go to the right side to place a low center. In haste Aubameyang for a simple tap-in.

It should have been finished. Arsenal 2-0 at halftime and yet, they were the makers of their own fall, putting pressure on themselves by trying to faint from behind.

Bernd Leno played against Sokratis, his pass was intercepted by Gerard Deulofeu and Tom Cleverley broke the score after 53 minutes.

The goal changed the mood and Emery's substitutions then transferred the initiative to Watford. Attack after attack, Arsenal found himself stuck in the back, they were not hanging on anything.

Watford had the equalizer after 81 minutes. Luiz launched a stupid challenge, suspending a leg that tripped Roberto Pereyra and the substitute fired at home. Arsenal had managed to throw it away.

The only relief for Arsenal was not to lose because Abdoulaye Doucoure had a great chance of succeeding in overtime and that only a last Leno rescue prevented an even greater embarrassment.
