Mikel Arteta believes Willian is the player who can drive Arsenal towards a push for more silverware and a top-four finish.
Willian, 32, signed a three-year deal with Arsenal in August after leaving Chelsea as a free agent.
The playmaker – who joined Chelsea from Shakhtar Donetsk in 2013 – scored 37 goals and provided 33 assists in 234 Premier League appearances for the Blues.
