As many French children of his generation, Lacazette grew up watching the intense rivalry between Wenger's Arsenal and Sir Alex Fergson's Manchester United in awe, hoping one day to be a part of it.
His move to the 'Gunners' from Lyon in the summer made that dream a reality and now with Wenger set to leave at the end of the season, Lacazette wants to make sure his boss goes out on a high as his team travel to Old Trafford on Sunday.
"Since I was young I was dreaming about this kind of game, when Thierry Henry and everybody scored some goals," Lacazette told the 'Daily Mail'.
"Of course I knew about the rivalry. I remember Sylvain Wiltord's goal in the gold shirt [in 2002 to win the title]. I was a real fan. But now it is for me to play and have a good performance as well.
"For every French person, Arsene Wenger is a great manager. He was 22 years in the club so he has a good image in France and for a player like me we want to finish well for him.
He continued: "I saw him before I signed and we talked for a long time because it was a big decision to change my life. I'm always thankful to him because he believed in me to come from France and go to Arsenal.
"It will be hard because I have never been to Old Trafford but I know every time you go there it is hard. When you play for Arsenal these kind of games come every three days - we're having a lot of big games and little recovery but we just want to keep going and put on a good performance."
