Arsenal boss Unai Emery is unsure if David Luiz will be clear to face Manchester United on Sunday.
Arsenal are waiting to discover if new signing David Luiz will get international clearance in time to make his debut against Newcastle on Sunday.
Emery said: “At the moment we need confirmation if he is OK for the federation to play Sunday. On Friday morning he trained with us but not all because he was in London doing the visa.
"So Saturday he is going to be training with us for the first day, l will decide then but I have confidence in Sokratis and Calum Chambers."
