Arsenal signing Willian admits David Luiz is delighted with his arrival from Chelsea.

Willian admitted his countryman and former Chelsea team-mate David Luiz lured him into joining Arsenal.

"He [Luiz] is very happy. We played together in the national team, we played together at Chelsea, and now at Arsenal again," he told the club's website.

"I think we can do great things together, I hope so, but I'm very happy to be with him again.

"He said, 'Come to Arsenal, come to Arsenal, I want you to come!' So that was the conversation."
