Manchester City picked up where they left off last season with a dominant performance to win 2-0 at Arsenal.
It is worth noting that the defending Premier League champions unpicked the opposition on Unai Emery's debut without Gabriel Jesus, Fabian Delph, Leroy Sane, David Silva, Nicolas Otamendi and Kevin De Bruyne in the starting line-up. In other words, six of their 11 most frequently-used players from last season were missing, when they set a new Premier League points total with 100.
The scary bit for rivals is the seamless way in which Pep Guardiola can change personnel and not miss a beat.
