The 26-year-old will soon join up with the rest of the Gunners squad for pre-season training in July after he's penned a five-year contract.
Lyon striker Alexandre Lacazette has passed his Arsenal medical and is on the brink of completing a £46 million transfer to the Premier League club.
The 26-year-old underwent a medical at London Colney training ground on Tuesday and is expected to sign a five-year contract for a club-record fee, eclipsing the £42.5m paid to Real Madrid to sign Mesut Ozil in 2013.
With hopes of signing Monaco's Kylian Mbappe - a Real Madrid and Paris Saint-Germain target - fading, Arsenal manager Arsene Wenger managed to convince another of Ligue 1's star forwards to play at the Emirates Stadium.
Lyon club president Jean-Michel Aulas, who sanctioned the transfer on Sunday, has previously said the Premier League side must part with €65m to prise Lacazette away from Parc Olympique Lyonnais and the newly agreed deal includes bonuses worth £6m.
Kenneth Omeruo
In other news, Chelsea have received an offer from Goztepe to sign Kenneth Omeruo, according to reports.
Omeruo, 23, joined the Blues from Standard Liege in January 2012 but he has failed to make a single first-team appearance.
He has been loaned out four times with his latest spell being with Turkish side Alanyaspor, where he made 26 Super Lig appearances and scored one goal.
This was the Nigeria international’s second spell in Turkey after previously spending time on loan at Kasimpasa.
Omeruo has two years remaining on his contract at Chelsea, but securing first-team action at the club seems very unlikely.
And Turkish outlet Fotomac say Goztepe are interested in offering him the chance to secure regular first-team football.
The newly-promoted side are said to have entered the race alongside Sivasspor to sign the centre-back.
But Goztepe appear to be the frontrunners for his signature with their offer being more attractive.
