That is the belief of Dion Dublin after their north London derby defeat of Tottenham.
The Gunners have yet to be leading in a Premier League game at half-time and despite taking the lead at home to Spurs found themselves in the same situation again at the Emirates.
Pierre-Emerick Aubameyang’s penalty was cancelled out by an Eric Dier header and a Harry Kane spot-kick as the visitors went into the break 2-1 up.
But Aubameyang levelled with a brilliant strike before quick-fire goals from substitute Alexandre Lacazette and Lucas Torreira – both supplied by another introduction from the bench, Aaron Ramsey – extended Arsenal’s unbeaten run to 19 games in all competitions.
Arsenal would be 19th if Premier League matches finished at half-time this season but they have shown second-half steel under Emery by scoring 24 league goals after the interval.
The Spanish coach has done wonders in north London with Arsenal’s chances of sealing a Champions League spot having been written off after opening their campaign with back-to-back defeats to Manchester City and Chelsea.
Yet they sit fourth after 14 games and are eight points clear of sixth as they seek their first finish in the top four since 2015-16.
Their final two seasons under Wenger were marred by defensive inconsistency and a lack of spirit and heart, having leaked 51 goals last season and suffered 13 defeats.
But ex-striker Dublin – who scored 111 Premier League goals in 312 appearances – thinks that Arsenal are developing into a tougher team.
“What I like about the Arsenal of late is that they’re listening to the manager and they’re doing what the manager wants them to do,” he told Monday Night Football.
“They’ve got a little bit of personality about them. Very much the swagger they had with [Emmanuel] Petit and [Patrick] Vieira in there.
“They know they’re good but now they’re bringing those performances to the table as well.
“Whereas before they had great personnel, nobody was brave enough to say, ‘Oh I’m not sure.’ Aubameyang’s doing it and Ramsey doesn’t mind.
“There had to be goals in a game like this [against Spurs], there’s too much quality on show going forward.
“I didn’t expect as many as I saw. And I did not expect Arsenal to have it in their locker to come back like they did.
“I really didn’t. That soft underbelly that Arsenal had is now on its way out. It’s becoming a habit.”
Arsenal face another stringent examination of their top-four credentials tomorrow night when they face Manchester United at Old Trafford (8pm) – a stadium where they are winless in 12 years.
