Willian still has the desire and ambition to be a driving force in the Premier League, according to Arsenal manager Mikel Arteta.
Arsenal's financial situation has been the subject of much scrutiny in recent months, but Mikel Arteta is on board.
Gabriel Martinelli made a big impact at Arsenal before being struck down by injury and Willian is expecting big things from his team-mate.
Ashley Cole thinks Willian is a shrewd piece of business but warned Arsenal need to do whatever they can to keep Pierre-Emerick Aubameyang.
Willian joins a notable list of names to play for both Arsenal and Chelsea in the Premier League era.
Arsenal confirmed the arrival of Willian on Friday and Mikel Arteta is delighted to have the experienced former Chelsea player in his ranks.
After weeks of speculation, Willian's move to Arsenal after he opted to leave Chelsea has been completed.
Having been strongly linked to Arsenal for a while, Willian will confirm his next destination soon, says Kia Joorabchian.
As rumours over a switch to Arsenal continue, Willian has confirmed he is bringing his seven-year spell at Chelsea to an end.
