Lacazette scored 37 goals in 45 games for Lyon last season, and sources in France have assured that a £50 million deal has been agreed to bring the striker to the Emirates.
The 26-year-old's arrival will happen shortly, as reported by 'L'Equipe', with Alexis Sanchez ready to quit Arsenal for City. The French striker would take the Chilean's place, but the Gunners will be made to pay for the centre-forward.
If Sanchez eventually stays at Arsenal, the striker would form a deadly partnership with the Frenchman, making the Gunners serious contenders for the Premier League title.
