Willian insists he is learning a lot under Arsenal manager Mikel Arteta but has admitted elements of the Spaniard's tactics have often left him 'frustrated'.
The winger joined the Gunners on a free transfer in the summer after rejecting a new contract at Chelsea and found adapting to life under his new coach, who wants his players to hold their positions and wait for the ball to come to them.
The Brazilian has not been able to make an impact since his two assists in the opening game against Fulham and is still waiting for his first goal in an Arsenal shirt.
