There has been a lot to admire about Arsenal in the attacking phase so far, as many predicted there would be.
Nicolas Pepe, although yet to score, looks bright and the quality of both Pierre-Emerick Aubameyang and Alexandre Lacazette is undeniable.
One would imagine the Gunners are going to wallop a few teams this season once all three really get up to speed.
But the biggest concern, again, as many predicted, is that the defence will make life nervy and uncomfortable for Emery’s side.
So far, David Luiz – whose £8 million transfer from Chelsea was generally praised – has made mistakes, as has his partner Sokratis whose rash nature was again on show at the weekend against Tottenham Hotspur.
The pair have featured three times together so far and have failed to keep a clean sheet, conceding six goals in the process.
The club’s only clean sheet came on the opening day against Newcastle United – a game started by Calum Chambers.
Emery should surely be considering recalling Chambers after the international break, if anything to restore a bit of calm at the back.
The poise the Englishman showed against the Magpies is exactly what Arsenal have lacked in recent weeks.
Luiz and Sokratis are too overly enthusiastic and are struggling to make a strong case to be played in a partnership.
With Rob Holding still working his way back to full fitness and Shkodran Mustafi simply too error-prone, Chambers could well be the answer as Arsenal seek to tighten up ahead of some favourable upcoming fixtures.
Interestingly, Chambers also has the ability to play as a holding midfielder – with Granit Xhaka having also disappointed there could be even greater demand for the former Fulham loanee.
