Lacazette has bagged seven goals so far this campaign and appears happy in north London.
There is no suggestion he wants to leave nor is there that the club are considering offloading the clinical finisher.
Compatriot Chris Mavinga, who has played with Lacazette through the France youth set-up, was watching from the stands.
Midway through the game, the Toronto defender tweeted a picture of his view, saying: “Scouting day at emirates stadium .. next challenge trying to bring @LacazetteAlex in @torontofc @mls."
Lacazette then replied to his friend, posting two shrug emojis and a smirking emoji, saying: “Ahaha maybe in the future."
