Willian joined Chelsea's London rivals Arsenal on a free transfer in August 2020, signing a three-year deal with the Gunners. He is still yet to score for his new club, although he has provided seven assists this season.
The Brazilian has spoken about Arsenal's mentality during a week in which they face Czech side Slavia Prague in a huge quarter final clash in the Europa League. The side from London arrive on the back of a 3-0 thumping by Liverpool on Saturday and will be hoping to bounce back in Thursday's game.
The winner will face either Dinamo Zagreb or Villarreal in the semi finals.
