Arsenal fans immediately noticed how Chelsea's official X account reacted to Kai Havertz's goals against his old side.
Havertz scored a brace as Arsenal destroyed Chelsea 5-0 at the Emirates on Tuesday.
He scored his team's third goal then brought up their fourth moments later.
Havertz netted his first goal of the night when Martin Odegaard picked him out with a stunning pass.

The German held off Marc Cucurella before slotting home. He wheeled away in celebration in front of a jubilant home end.
Chelsea, who named the scorers for the first and second goal on X, refused to name Havertz following his strike.
"Goal for the Gunners," the club wrote on social media. For his second goal, they wrote: "Goal to Arsenal."
Chelsea failing to name Havertz on X didn't go unnoticed among Arsenal supporters on social media.
One X user joked: "Who scored?"
A second tweeted: "Go on who scored lads."
A third added: "SAY HIS NAMEEEEEEEE."
A fourth said: "Don’t be shy tell us who scored it."
Another wrote: "It's paining them and I love it."
Leandro Trossand opened the scoring in just the fourth minute. Like Havertz, Ben White bagged a brace as Arsenal secured all three points and bragging rights over their London rivals.
Arsenal, who sit at the top of the league, move three points clear of Liverpool and four points ahead of Manchester City, who have two games in hand.
Mikel Arteta's charges resume their league campaign on Sunday when they travel to neighbours Tottenham.
