Willian says he was persuaded to join Arsenal by the Mikel Arteta project and is eager to help the club get back to challenging for the Premier League and in Europe.
The Brazil international, 32, has signed as a free agent on a three-year contract at the Emirates after calling time on seven years at Chelsea where he won five major honours.
Asked why he decided to move across London, Willian told Arsenal Digital: “Arsenal is one of the biggest clubs in the world and because of the new project with Arteta.
“I think this club deserves to shine again. I want to be a part of this project, to be part of the Arsenal family, it’s amazing, I’m very happy to do that.
On what he likes about the club, he added: “[I like] the way they play, everything is amazing – the stadium, and I think that with Arteta, Arsenal have a great opportunity to fight again for titles in the Premier League and in Europe so I’m very happy because of that.
“I’m excited to start. I can’t wait to go on the pitch and do my thing to help my team-mates and to help this club to shine again. That’s what I want.
“When I talked to [Mikel], the conversation was good, he gave me confidence to come to Arsenal. He said a lot of good things to me and that’s why I have come to Arsenal.”
There’s been speculation that Willian could challenge for a role in the centre of midfield having made his name as a wide player. On where he’ll fit in, he joked: “Haha, that’s a difficult question – I don’t know! I leave that to Arteta,” he said. “I come to help in every position.
“I can play on the right, I can play in the middle, I can play on the left side as well. So I want to help – in any position where they put me to play, I will try to do my best.
“This club deserves to win again. We have to do our best to win every game, I’ll always train hard and go on the pitch 100 % to help this club win games and titles.”
