Arsenal are moving to sign Pierre-Emerick Aubameyang and Henrikh Mkhitaryan has appeared to goad his former teammate after completing his own move to north London, Mirror reported.
The club released a video of Mkhitaryan's first day in north London after completing his move from Manchester United.
It is a small segment in which Mkhitaryan mouths something that appears to be inaudible.
But fans are speculating that Mkhitaryan said: "Yo Pierre, you wanna come out here?"
The 29-year-old Armenia midfielder on Monday signed a long-term contract with Arsenal. Henrikh Mkhitaryan will wear the No.7 shirt vacated by Alexis Sanchez.
Henrikh Mkhitaryan's weekly wage will make £180,000, thus, he will be the Arsenal's second highest-paid player.
