The Gunners were threatening to come back into the match with City leading by Raheem Sterling's early goal, but Bernardo's top-corner effort was as perfectly timed off his laces as it was on the clock.
Man City's domestic success has been well documented over the last few years, while Arsenal have failed to finish in the top four of the EPL in back-to-back seasons for the first time since 1996.

Speculation about Pogba’s future at United continues to mount
Pogba , who was given the captaincy by Mourinho on Friday, summed up what it meant for him to be happy and comfortable. I came back on Monday so it was very hard for the legs and the stamina but we played very well.
Guardiola insists his players are still "starving" for success and there is little doubt City's hunger for silverware remains strong.

Giles said the spotlight on the animals, while itself disgusting news, has already led to skyrocketing worry about their plight. During the first three days of her calf's death, the orca swam with her pod but carried along her baby's almost 400 pound body.
But that noisy optimism was punctured in ruthless style by Sterling in the 14th minute.
Arsenal finally threatened when Bellerin's blast forced City goalkeeper Ederson to make a good stop.
