In a not-so-subtle dig aimed at Pierre-Emerick Aubameyang, Arsenal defender Gabriel Magalhaes tweeted out "nothing personal - London is red" after his goal helped the Gunners beat Chelsea.
Earlier this week, in the build-up to Sunday's Premier League clash at Stamford Bridge, former Arsenal striker Aubameyang made some bold statements in his promotional advert with BT Sport.
He looked straight down the camera lense and said: "Arsenal, nothing personal. I'm back, I'm blue, I'm ready. Let's go."
The below footage shows Aubameyang was told exactly what to say by someone behind the camera, but that hasn't stopped Gunners fans from celebrating a win against their former player.
The dominant victory at the Bridge came courtesy of a second-half goal from defender Gabriel Magalhaes, who took to social media after the 1-0 win to make his voice heard.

His tweet: "NOTHING PERSONAL .. LONDON IS RED," picked up over 150,000 likes in the space of an hour.
Aubameyang, meanwhile, endured an afternoon to forget against his former club. In fact, the Gabon international only managed eight touches of the ball before being subbed off in the 64th minute.
He also received more yellow cards [1] than he had shots during the Premier League fixture.
All the talk ahead of Sunday's clash at Stamford Bridge was about Aubameyang's return against Arsenal.
Last year, the 33-year-old was stripped of the Arsenal captaincy following a breach of discipline in December, with the striker reportedly returning late from a trip abroad.
He was then left out of Mikel Arteta's first-team plans until he joined Barcelona in a late January move.
After a hit and miss spell in Spain, he eventually joined Chelsea this summer, although his comments about Mikel Arteta in October earned more headlines.
In a clip that circulated on social media, he slammed Arteta for being unable to handle senior players in the dressing room.
"Big characters and big players...he can't deal with it. He needs some young players who don't say anything,” said Aubayemang in the video.
He later posted an apologetic tweet addressing the leaked footage.
