Soon after Unai Emery was appointed as the new boss at the Emirates Stadium, it quickly emerged that the new Gunners boss was looking to bring in Lichtsteiner on a free transfer.
The Switzerland international has spent the last seven seasons in Turin, but the full-back will now link up with the Premier League outfit once his Juventus deal has expired at the end of the month.
Emery told the club's official website: "Stephan brings huge experience and leadership to our squad. He's a player with great quality with a very positive and determined attitude. Stephan will improve us on and off the pitch."
Lichtsteiner will leave Juventus having made 250 appearances for the Italian giants in all competitions.
