The French striker is set to seal a five-year deal with the Gunners as Arsene Wenger makes an early move in the transfer window.
The 26-year-old agreed personal terms on an £150,000-a-week contract over the weekend.
He arrived at Arsenal‘s London Colney base, Herts, yesterday where his official pictures will be taken before being unveiled.
The forward will also be introduced to his new team-mates who have returned for the first day of pre-season.
Lacazette scored 37 goals in 45 appearances last season and will give Arsenal‘s frontline a huge boost.
