Arsenal star Gabriel mocked former teammate Pierre-Emerick Aubameyang as the Gunners defeated Chelsea 1-0 at Stamford Bridge on Sunday.

Gabriel’s second-half tap-in consigned the Blues to their fourth defeat of the season.

In the build-up to the game, Aubameyang, who was facing his former side for the first time since his departure last January, warned Mikel Arteta’s side, saying, "I’m back.”

Gabriel marshaled Aubameyang throughout the game and stopped him from getting close.

The Brazilian took to Twitter and cited Aubameyang’s BT Sport promo and reminded him that “London is Red."

“Nothing personal. London is red,” Gabriel wrote in capital letters.
