Willian has become the latest player to swap west London for N5 - and says helping the club to "shine again" is a key motivator for him.
The Brazil international became our first signing of the summer after joining on a free transfer from Chelsea, and he's looking forward to the challenge.
"I'm very excited to become an Arsenal player - I can't wait to start training and playing with my team-mates," Willian told Arsenal Digital.
"I decided [to join] because Arsenal is one of the biggest clubs in the world. They have a new project with Mikel Arteta.
"I think this club deserves to shine again and I want to be a part of this project - to be a part of the Arsenal family is amazing. I'm very happy to do that.
"I come to try to win trophies, because this club deserves to win again, and I think you have to do the best as possible to win every game. I always train hard and go on the pitch giving 100 per cent to help this team to win games and to win titles as well."
