Newcastle United have seemingly aimed a jibe at Arsenal boss Mikel Arteta following their Carabao Cup semi-final exit.

The Gunners fell to a 2-0 defeat to Newcastle in the second leg of their League Cup semi-final on Wednesday night at St James' Park. Goals from Jacob Murphy and Anthony Gordon handed Arsenal a 4-0 aggregate defeat as they failed to reach another Wembley final.

The loss means that Arsenal's remaining chances of silverware rest on the Premier League and the Champions League. After the game, Newcastle posted on X (formerly known as Twitter) which was captioned: "The culprit" and featured a photo of the match ball.

This appeared to be in reference to comments made by Arteta after the first-leg defeat at the Emirates Stadium, where the Arsenal boss suggested the match ball used in the Carabao Cup is "different" to the one used in the Premier League.

"No, it’s just different," said Arteta on January 7. "Very different to a Premier League ball, and you have to adapt to that because it flies different, when you touch it the grip is very different as well so you adapt to that."

A few days later, Arteta was once again asked about the prospect of using a different ball to the Premier League, when they faced Manchester United in the FA Cup. Arteta explained his previous comments as to what he meant when he compared the match balls used in different competitions.

"In Champions League it’s different, you’re relating to the question I got the other day about the ball and what I said is every ball is different. Champions League ball is different, grip different, fly different, feel different," said Arteta on January 10.

"That’s it, it's not an excuse it's a reality every pitch is different. Weather conditions change in football that’s the beauty of it. Never an excuse."
