Arsenal fight back to beat Tottenham in fiery derby
Pierre-Emerick Aubameyang is the first player to reach 10 goals in the Premier League this season
The manner in which Arsenal pressed and powered Spurs into submission here was remarkable but further evidence of their transformation under Emery.
The former Sevilla and Paris St-Germain manager has galvanised the club on and off the pitch after the stale end to the Wenger era. He was a constant blur of movement in his technical area almost guiding every move by hand.
Emery has, crucially, made an instant connection with Arsenal's fans, regularly urging them to turn up the volume at moments when the stadium threatened to go quiet.
Arsenal simply refused to give an inch to Spurs and Emery was bold when Spurs led at half-time, sending on Lacazette and Ramsey.
His side had not played well in the first half, but the changes gave them a turbo-charge.
It was said the true test of Emery's work would come when they faced their closest rivals. This was an examination they passed with flying colours.
Spurs and manager Mauricio Pochettino have made their name with the intensity of their attacking, pressing style backed up by obvious quality.
Here, however, they had all their own strengths turned back on them by Arsenal and almost seemed in a daze as they were swept aside in the latter stages.

Arsenal had Spurs in trouble instantly and barely let go, even when Dier and Kane somehow had the visitors going in at the interval ahead.
Spurs could not create in attack, were impotent in midfield and vulnerable at the back where Vertonghen's uncomfortable afternoon saw him concede a penalty and receive a red card - while youngster Juan Foyth was punished for giving the ball away when Lacazette putting Arsenal in front.

They now lie outside the top four but will surely come again. Here, however, they were comprehensively outplayed.
