Arsenal left-back Kieran Tierney took to social media to apologise after a picture was shared online of him putting his middle finger up following the club's 2-0 win over Manchester City.
The now deleted picture showed the the entire squad celebrating with fans on Twitter quick to spot and point out Tierney's gesture.
Tierney, 23, has struggled with injury since joining the Gunners from Celtic in 2019 and seemed to acknowledge his joke may not have gone down too well with everyone online.
"Didn’t realise this was getting posted," Tierney said on Twitter in reference to the picture.
"Was a joke with the kitman. I’m so sorry if it caused anyone offence - wasn’t meant in anyway."
Thankfully for Tierney, most fans weren't offended, with one that is currently battling cancer seeing the lighter side of the joke.
Tierney was quick to acknowledge the Gunners supporter, urging him to keep fighting and promising to send him his Arsenal jersey worn in the club's 2-0 win over Manchester City on Saturday.
The Scottish defender was a class act on and off the pitch on Saturday as he starred in the club's FA Cup semi-final win.
Along with the clean sheet, Tierney claimed the assist for Pierre-Emerick Aubameyang's second goal with a fantastic pass, and is hopeful the Gunners can now kick on to bigger and better things moving forward.
"It was tough, we knew we would have less of the ball against City and you have to take your chances when you get them. Aubameyang does what he does," Tierney told BBC's Match of the Day.
"We have to suffer together in games like this, When we get the ball we have to play well but we know we will have 5-10 minute spells when we won't see the ball.
"Aubameyang has done it for so long, it's an honour for me to play with him. That ball I played isn't a goal-scoring ball but he makes it one.
"We are building for something big."
Arsenal will now face either Chelsea or Manchester United in the FA Cup final next month at Wembley, where a win for the Gunners would guarantee their place in the Europa League next season.
