Arsène Wenger's regime had long turned stale and in his place arrived a new a man, more than twenty years his junior, who seemed ready to shake things up, introduce new ideas and drive the Gunners back up the table.
After seven games Arsenal sit fifth in the Premier League and have won their last five top flight fixtures. So far, so good. Right?
Well we put Emery's start at Arsenal to the numbers in the latest episode of Three Minute Myths and found that – so far – he's hardly revolutionised their style of play.
Compared with his final season at Paris Saint-Germain – during which Emery had his side play in a very similar way to Wenger's Arsenal – the Spaniard has struggled to get his new crop of players to adapt to his tactics.
And to make matters potentially worse, Emery is deploying his star men out of position and blunting their effectiveness. So in this week's episode we look at what this all means for the Gunners going forward.
