According to Talksport2 both Alexandre Lacazette and Pierre Emerick-Aubamayeng have signed new deals with the club that would certainly be the icing on the cake of this transfer window.

There was some stupid talk about Aubameyang being shipped out this window but it didn’t last long and now it seems like he’s extended his deal along with his best mate, Laca.
These two make me so happy. https://t.co/RpFL1wtQq2 pic.twitter.com/U0sO5omSnO

Lacazette’s contract ran until 2022 while Aubameyang’s expired in 2021.
It’s not clear yet how long the extensions are for but we can assume they got a payrise from some of that £500k Arsenal have trimmed off their weekly wage bill this summer.
However, it’s worth noting:
And no plans to announce any new contracts today either. Obviously Arsenal want Aubameyang and Lacazette to stay and are confident that they will but club sources say nothing agreed.
