It's been suggested Lacazette could leave if Aubameyang chose to stay next season.
But he insists: "No, because we know that Auba has a lot of discussions with the club and I cannot put my future on anyone else.
"When he came, everyone knows we had a good relationship. We always talk about everything, not just about football but everything in life. He's a good guy. That's why it became really easy between us.
"I am happy with my career because I played for Lyon, my club since I was a child. I have played for Arsenal, my dream club in the UK. I'm still happy with my career but obviously I would like to win more trophies and this (FA Cup) can make me happier in my Arsenal journey."
