The club must lodge the necessary paperwork with the FA by 1pm on Thursday, with Arsenal officials eager to have the matter settled before Sunday's encounter with Liverpool at Anfield.

Arsenal manager Mikel Arteta remained fairly cautious when questioned about Dowman's sending-off. Speaking in his post-match press conference, he said: "I haven't seen it back, and with the camera you can't really see what happens.

"The decision was made by the referee, and that's it. Even with 10 men, we had three big chances to score. We know when we prepare the context of the match, we're very clear on what to expect. Emotionally, we have to dominate, but we're very clear."

Arteta was also seen delivering a furious response to Dowman following his red card, though the Arsenal manager chose to keep quiet about the specifics of their exchange. The Gunners boss added: "It's something that we discussed before the game."

"He wasn't having the greatest of nights so he's going to get frustrated. He gets the chance every now and then to play for Arsenal.

"If that's Viktor Gyokeres, he [Arteta] isn't doing that. That's what I don't like. If it's an experienced international, I don't think he does that. He's a human being. He's not the last person to get sent off for Arsenal and he's not the first."

The 16-year-old Dowman made his Arsenal debut last season, going on to rack up 13 appearances across all competitions. He netted a memorable goal against Everton to edge the North London club closer to Premier League glory.

He also bagged a brace in Arsenal's victory over Ipswich in the previous Carabao Cup round. Arsenal's run in the tournament was ultimately brought to an end as they fell to a penalty shootout defeat against Fleetwood, with Bruno Guimaraes seeing his spot kick saved.
