Arsenal lost 2-0 to the current English Premier League Champions at the Emirates Stadium.
Man City who beat Arsenal last season at the Emirate repeated the feat.
A 14th minute goal from Rahim Sterling gave City the perfect start.
Sterling weaved his way past opponents, and unleashed a magnificent effort from the edge of the box to make it 1-0 to City.
They had several half chances but could not double their lead as the first half ended 1-0.
Manchester City had to wait till the 64th minute to double thier lead withh Benjamin Mendy sliding a pass to Bernardo Silva who finished off with a beautiful shot.
That killed the confidence of Arsenal and Man City held on comfortably to secure all three points.
