Arsenal have confirmed the signing of Switzerland midfielder Granit Xhaka from Borussia Monchengladbach.
Sky sources reported at the weekend that Xhaka was in the process of completing the move for a fee in the region of £30m - Arsenal's third-most expensive transfer.
Xhaka subsequently completed his medical and will join up with his new team-mates after Euro 2016, where he is expected to star for Switzerland.
The 23-year-old has been among the outstanding central-midfield performers in the Bundesliga in recent seasons.
Arsenal boss Arsene Wenger said: "Granit is an exciting young player, already with good Champions League and Bundesliga experience.
"We have been watching him for a long time now and he is a player who will add quality to our squad.
