"I believe he's a player that can really make a difference for us. We have been monitoring him for the past few months, we had a clear intention to strengthen in the attacking midfielder and the winger positions [and] he is a player that gives us a lot of versatility, he can play in three or four different positions," Mikel Arteta said in an official statement.
"He has the experience of everything in the football world but to still have the ambition to come here and contribute to bring the club where it belongs. I have been really impressed with all the talks I have had with him and how much he wanted to come," he added.

He made 339 appearances, with 63 goals and 56 assists in that time.Willian has made 70 appearances and has scored nine goals for Brazil, making his international debut in 2011. He has since represented his country at the 2014 and 2018 World Cups, the 2015 Copa America, the Copa America Centenario, and the 2019 Copa America where he was a key member of the squad that lifted the trophy on home soil.Technical director Edu said: "I know him very well, since a long time ago because we've been working together for the Brazilian national team and of course I was following him because he played for another club. He has a lot of fantastic attributes as a person, as a football player of course, his character. I'm 100 per cent sure that everybody in the dressing room, the fans, myself and Mikel will enjoy having Willian in our side."
