Aston Villa have splashed out to land Bayer Leverkusen winger Moussa Diaby.
The France international moves to Villa for a reported 60m fee.
"I will always look back happily and gratefully on my time in Leverkusen," said Diaby. "Now I want to take the next step, start a new chapter."
The midfielder has joined Villa for their US preseason tour.
Villa boss Unai Emery said: "We were following him. He is trying to help us improve our number in the attacking third. We are really excited and happy with him.
"He has experience in Europe. He is young. He can play in different positions."
