5 things we learnt from Manchester City's win against Arsenal

#3 Arsenal's defence needs a revamp

Goalkeeper Bernd Leno needs to start the next match. Cech looked nervy on the ball and was slow to react for the first goal. Bellerin kept getting beaten for pace by Sterling and his crosses were wasteful.

Sokratis was Arsenal's best defender but that's not saying much. His yellow card just outside the box exposed his lack of pace. Mustafi struggled with the Manchester City pace as well, looked nervy on the ball and was generally all over the place.

Ainsley Maitland-Niles was unlucky to pick an injury but Lichsteiner slotted in well at left back and brought stability in the defence.
