Willian trained as an Arsenal player for the first time on Friday as preparations towards the new Premier League campaign stepped up at London Colney.
The Brazilian was seen training alongside David Luiz and fellow attacking players, Pierre-Emerick Aubameyang and Nicolas Pepe at the St Albans training base.
Willian was Arsenal first summer signing, and this week followed it up with Gabriel from Lille.
Manager Mikel Arteta has lured the Brazilian across London from Chelsea on a free transfer, after Willian's Chelsea contract expired.
The player was open to staying at Stamford Bridge but Frank Lampard was unwilling to offer the three-year contract Willian wanted. The Gunners obliged and Willian went north.
Arsenal's reduced pre-season plans meant they only entertained MK Dons before beating Liverpool in the Community Shield last weekened.
Fulham are their first opponents of the new domestic season, with the Gunners travelling to Craven Cottage for the first game of the entire campaign.
