Emirates club welcome Stadio Friuli club for Champions League qualifier.
Marouane Chamakh v Danilo
With striker Robin van Persie suspended, manager Arsene Wenger will ask Chamakh to lead the attack.
He will be hoping the Morocco striker can recapture the form he showed at the start of last season but has not found the back of the net since March.
Danilo joined Udinese from Palmeiras in the summer and will be keen to make an impression at Emirates.
