Positives and negatives taken as Arsenal suffer first defeat in Premier League
Arsenal blogger James McNicholas writes on the point.
"The Unai Emery era at Arsenal began with a defeat as champions Manchester City reasserted their credentials in a 2-0 win. Raheem Sterling gave City the lead in a first half they dominated. Arsenal improved after the break, but not enough to stop Bernardo Silva putting the seal on the victory."
"Set what happened on the pitch aside, this was a huge day for Arsenal. It was the dawn of a new era, and it was encouraging to see the stadium packed full. In this precise fixture last season, there were whole areas in the stands that appeared empty.
"Perhaps the other big positive is that there were clear signs of a plan behind Arsenal's play. This was not the free-form football that frequently undid them under Arsene Wenger. Emery will need time, but there was evidence of his organisational streak coming into play."
"The gulf between City and Arsenal was plain to see. On this evidence, Emery also has lots of work to do to ensure the Gunners have a robust-enough defence to challenge seriously for the top four.
"An injury to Ainsley Maitland-Niles is a significant blow, especially with Sead Kolasinac already sidelined. Emery hinted that Danny Welbeck has been filling in at left-back in training, but surely nobody actually wants to see that come to pass."
