Everton completed the signing of Alex Iwobi on transfer deadline day in a deal worth a staggering £34 million, according to BBC Sport.
The Nigerian international has put pen-to-paper on a five-year contract at Goodison Park and has now started training with his new team.
Iwobi rose through the youth ranks with the Gunners. He went onto play 149 times for the club, scoring 15 goals and registering 27 assists.

Regular game time will be a big factor in Iwobi swapping the Emirates Stadium for Goodison Park and he will hope to hit the ground running.
One man who Iwobi will know at Everton from his time at Arsenal is Theo Walcott. Perhaps bizarrely the two may now compete for a place in Marco Silva’s team, given that they both operate in similar areas of the pitch.
The club’s official Twitter account has tweeted some video footage of Iwobi joining in on the training pitch this week.

It actually highlights Walcott and Iwobi linking up and supporters have taken to social media to tweet regarding Iwobi and his contribution.
It would appear some are keen to see him in action for the Toffees and we looked at a selection of tweets from Everton supporters:
