Thomas Partey sent Arsenal fans an apology message following the 2-0 loss to Liverpool in Thursday night's Carabao Cup semi-final second leg.
The Gunners went into the match full of confidence after delivering a resolute display at Anfield in the first leg, securing a 0-0 draw despite playing over an hour with just 10 men.
However, they were unable to take control of the game as Portuguese international Diogo Jota scored in both halves to secure the Reds a spot in next month's final at Wembley against Chelsea.
To make matters worse, tough-tackling midfielder Partey received his marching orders in the last minute after referee Martin Atkinson brandished two quick-fire yellow cards to the 28-year-old, who had come on as a substitute late in the second half.
The former Atletico Madrid star only arrived back in London from an unsuccessful Africa Cup of Nations campaign with Ghana on Thursday afternoon, and will now miss the must-win clash against Burnley this weekend.
That leaves Albert Sambi Lokonga as the only senior central midfielder available to Mikel Arteta, with Granit Xhaka also suspended. And the Ghana International took to Instagram on Friday morning to apologise to the Arsenal faithful for his red card, claiming that he will work hard to rectify it.
He wrote: "Am responsible for anything that happened and will take all the critiques, I should get more intelligent not to get in a challenge already booked but this is my personality, I like to fight for every ball.
"I love this club and love my country even though things don't happen how I wanted, I would continue to work harder and make things right.
"I came back with the mentality to make myself available for the team to get to the final but it did not happen as planned.
"I will continue to give my all when am on the field of play because this is my life and this is what I chose to do.
"Am not happy with all that happened yesterday at the AFCON but I understand only with hard work things will continue to work hard to change this. Thanks."
