Xhaka was guilty after he tried to pass the back to David Luiz only for the ball to deflect off the body of Chris Wood into the Arsenal’s empty net.
The camera pounced on him following his error as he raised his arm in apology.
The draw saw Arsenal remain in 10th position in the league.
Meanwhile, Xhaka took to his Instagram page to offer his apology to the Arsenal team mates and fans.
He said, “I hold my hands up for their goal and I’m sorry for the mistake. That’s football and right now I feel just as frustrated as all of you.”
