It was Watford's first match since rehiring Quique Sanchez Flores as head coach after sacking Javi Gracia during the global break and Arsenal boss Unai Emery admitted his countryman's side gave them fits with their physical play. Arsenal countered through Kolasinac and the left back played a low pass to Aubameyang who swiveled on the ball before drilling past Foster into the bottom corner.
I am not digging out Ozil but I am highlighting the attitude that he is displaying, to me it is just not acknowledging how calamitous that second half was, it was literally one of the worse performances I have seen from Arsenal in a second half.
Flores, who left Watford in 2016 but returned to take over from the fired Javi Gracia, was left holding his head as Arsenal goalkeeper Bernd Leno denied Abdoulaye Doucoure what would have been a dramatic victor in injury time.
It was nearly 2-0 minutes later after Ceballos found Mesut Ã-zil, whose cross Aubameyang just failed to reach. The Arsenal right-back crossed to give Aubameyang a simple finish for his second goal, his fifth of the season.
But hold up, it gets worse, since the start of last season there have been 14 errors directly leading to goals by Arsenal players, that is two more than any other Premier League club.
Watford started the brighter of the two teams with Gerard Deulofeu looking unsafe down the left hand side and testing Leno with a curled right foot effort after five minutes.
The visitors continued to wobble as Watford continued to dominate.
Tom Cleverley took advantage of some slapstick defending by Sokratis Papastathopoulos to reduce the deficit, however, before Roberto Pereyra ensured a share of the spoils from the penalty spot after he had been brought down by David Luiz.
Richarlison produced a fine cross for Dominic Calvert-Lewin to equalize before the break.
Callum Wilson scored twice as Bournemouth curbed early-season optimism over Everton's prospects with a 3-1 win on Sunday. Substitute Ryan Fraser restored Bournemouth's lead in the 67th with a free kick that took a slight deflection off Fabian Delph.
Bournemouth midfielder Lewis Cook made his first start since December after recovering from anterior cruciate ligament damage to his right knee.
