Arsenal manager Mikel Arteta has confirmed center half David Luiz is out of their game against Dundalk on Thursday.

The Gunners play in the Europa League group stages, and Luiz will not feature from the start or on the bench.

He came off during the team's 1-0 defeat to Leicester City in the Premier League with an injury.

"There is no chance [David Luiz will face Dundalk]," Arteta said during a press conference.

"He's a big doubt for the weekend too.

"Willian is back in training, he might be involved at some stage.

"Bukayo Saka is fine, it was a knock, but he's fine."
