Iwobi now feels more confident going forward thanks to a data analyst, who sends him video footage of his performances - proving again the degree of Emery's attention to detail.
He told the club's website: "This season I feel much better and I feel like I'm in control, especially going forward in an attacking sense.
"I have an analyst now who is always trying to help me, which I didn't have in seasons before, so he's sending me clips and saying what I can do better."
But Iwobi thinks that stats do not always reflect a player's impact on his team, and believes the extra work he puts in has made him contribute more offensively at the Emirates.
He said: "That's helped me and I'd like to say I've been involved in a few goals this season, even it's not the assist or the goal, I've been getting a few pre-assists which go unnoticed.
"But at the end of the day as long as the team does well, that's my main concern."
