Mikel Arteta admits Willian has failed to live up to expectations and there is a ‘chance’ he could leave Arsenal before the summer transfer window closes.

The Gunners signed Willian on a free transfer after his contract with Chelsea expired at the end of the 2019/20 campaign and the 33-year-old started last term promisingly, registering a pair of assists on his debut against Fulham.
