Willian bought into Mikel Arteta's "incredible project" at Arsenal, according to his agent Kia Joorabchian, who says the ex-Chelsea star was "wooed" by the Arsenal boss.
Arsenal announced the arrival of Willian on a free transfer on August 14, as they snapped up the winger on a three-year deal following his departure from Stamford Bridge.
The 32-year-old was offered the chance to extend his stay at Chelsea, but the two parties ultimately failed to reach a final agreement over the length of his proposed contract.
