The striker of Lyon held in his home team 274 of the match in which he scored 127 goals and recorded 43 assists.
Lacazette came through the youth ranks and made his debut eight years ago.
Lacazette also revealed that he has spoken to Atletico Madrid, praising their players and facilities, but admitted that he has not agreed to sign for them just yet.
Lacazette, who has hit 26 Ligue 1 goals for Lyon this season, said he feels now is the right time to move on.
Lyon took the lead in the 10th minute when Nice defender Maxime Le Marchand inadvertently turned in forward Memphis Depay's shot.
"Alex has a verbal agreement with one club, Atletico".
But Lyon were not keen to let him go which saw them turn down a £30.1m ($37.6m) bid from the Gunners.More news: Billboard Music Awards: All the highlights
'I think that's the right time, ' Lacazette told L'Equipe.
I want to discover something else, to put myself under pressure and to gain a level. Although people say I score goals, I know I'm not very well known on a European scale. "I want to see if I can answer the questions people are asking of me and keep improving".
"It's a club that has been in the Champions League semifinals for a number of years". It's a great club with a great stadium and players make progress there. He also discussed the possibility of linking up with France team-mate Antoine Griezmann.
"It is I who chooses my future destination".
He told L'Equipe: "Yes, it's true, it would be a lovely story if we could carry on together (smiles)".
"No one wanted to harm anyone".
"Antoine has been trying to get me to move there for a while".
