Arsenal boss Mikel Arteta has revealed the club is yet to know the injury extend of defender David Luiz.
"We don't know. He was in pain the other day when he had to leave the pitch," said Arteta during Tuesday's press conference.
"He's not a player that normally does that, so he was uncomfortable. We assessed him yesterday and he was a bit better, but we don't know. He had a scan this morning as well to see how bad it is and he's very willing. He wants to play but he's always like that. We will have to see how he is."
On Mesut Ozil
Arteta was also asked if midfielder Mesut Ozil could feature for the Gunners against Norwich and he said, "The players want to play as well as possible, train as well as possible, and then it's a tricky game."
"You have momentum, you have your team-mates to help you as well and you need confidence. It's not just one factor but I never doubt that the players want to do their best."
The north London side will host Norwich City tomorrow at the Emirates starting from 8:00 PM EAT in a Premier League encounter.
