Talking points from Arsenal's opening game against Manchester City

3. Lot of work to do defensively

The decision to choose Cech over Leno did not go in vain: despite the veteran keeper's mistakes between the posts, he did make some crucial saves on Sunday.

Cech made 42 passes and only five of them went into the opponent's half. He made 57 touches in all making Matteo Guendouzi (with 72) the only Arsenal player to have more.

It became clear that Leno is more suited to play out from the back than Cech is, making the German better suited to the task that Emery has planned for his keepers.

Maitland-Niles struggled defensively but that is expected for such a young player who is not even technically a defender. Even the more experienced Sokratis struggled to stifle the fast Manchester City attack.

Despite having shown incredible character for a 19-year-old, young Guendouzi's inexperience was also evident throughout which leads to the question of why Emery overlooked the much-hyped Torreira and Mohamed Elneny to pick the youngster. The only time we looked solid defensively was when Lichtsteiner replaced Maitland-Niles in the second half.

Emery may have brought in replacements but he really needs to figure out how to make the best use of each of them.
