The 19-year-old has been with the squad since the summer and featured in friendlies against Aston Villa and MK Dons but hasn’t played since his Under-23s outing against Brighton in mid-September but isn’t even on the bench this evening.
Arteta has gone strong with Bernd Leno starting in goal and what looks like a back four ahead of him.
Cedric Soares comes in for Hector Bellerin at right-back, while Rob Holding and Gabriel Magalhaes partner each other at centre-back and Sead Kolasinac plays left-back.
The midfield is made up of Dani Ceballos, Granit Xhaka and Joe Willock and could shape up as either a midfield three or as a double pivot with either Willock or Ceballos as the No.10.
Xhaka will start as captain for the first team since he was stripped of the responsibility following his outburst at fans against Crystal Palace last season.
Moving to the front three, Nicolas Pepe returns on the right wing, while Eddie Nketiah leads the line and Bukayo Saka takes up the left wing.
Fans were also surprised to see Kolasinac start following rumours of his exit earlier in the week.
Heading into the game, Mikel Arteta didn’t hold a pre-match press conference, however, Jurgen Klopp’s assistant manager Pep Lijnders was on hand for Liverpool.
Asked about what he is expecting from Arteta in his second trip to Anfield in a week, he stressed just how strong the Gunners have been in domestic cups since the Spaniard. Of course, Arsenal beat Liverpool in the Community Shield but also swept Manchester City and Chelsea aside to lift the FA Cup in August.
“We go from Premier League to League Cup, so it’s a final,” Lijnders told reporters ahead of the game. Mikel won his last seven games in domestic cup[s] so it’s a completely different contest we are going to play [in] this game. It’s a proper win or lose,” he said ahead of the game.
“What Mikel has told at Arsenal, and what all good teams in Europe and the Premier League have is a clear identity. [Despite] changing players, it stays the same.
“They will try to improve for sure but that’s the same for us despite it’s only two days in between. The main thing is to recover well [and] regain freshness. Some had a day off yesterday to regain freshness mentally, emotionally and others will really prepare [for] this game.”
Although Arteta didn’t speak ahead of tonight’s game, he did before the third round win over Leicester City, when he made it clear that Arsenal are looking to take the Carabao Cup seriously.

“We are going to take the Carabao Cup seriously, that is for sure,” he said in September.
“Obviously with the fixtures we have, the number of games, it is very difficult. Maybe not in the first games but when the competition moves a little more forward, how teams – not just ourselves – are going to treat the competition.
“But we have to go day by day, lets see what position we are in for Wednesday to try and put out the strongest possible team to try and win it.”
