A hugely-experienced right-sided defender, Stephan made over 250 appearances for Juventus and is the fourth-most capped player in Switzerland history with 99 appearances for his country. He has also been the Swiss captain since 2016.
Stephan, who will wear the No 12 shirt and have his surname on his shirt, has spoken to Arsenal Media about his move – and you can watch the interview below.
Head coach Unai Emery said: 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.
Stephan, 34, started his senior career in 2001 with Swiss club Grasshopper Zurich, where he won the league title in 2003. He played in France with Lille for three years before moving to Lazio in Italy in 2008, where he won the Coppa Italia and the Supercoppa Italiana before moving to Juventus in 2011.
The deal is subject to the completion of regulatory processes.
Stephan, welcome to Arsenal. How does it feel to have joined the club?
It’s a great moment. It’s great for me after Juventus to come to Arsenal and have this big challenge to make big things happen with this big club.
What is it about Arsenal that attracted you, that made you want to move to London, to Arsenal and the Premier League?
There is a project. There is a project to come back into the Champions League. I think it’s hard to see a club like Arsenal not playing in the Champions League. If you see the players, if you see the club, the stadium… it’s the project, the big opportunity to get back to the highest level.
What are your memories of Arsenal over the years?
I’ve never played against Arsenal, but of course there was the big era of Wenger. He won a lot of titles with Arsenal and [made them] a big team. Now it’s a new moment. Wenger went and now everything is a bit new, so it’s a big challenge.
We have a new head coach, Unai Emery, so what do you know about him? It’s a new chapter for the club and a very interesting time for you to be joining…
He’s a very good coach who’s won a lot of titles, especially the Europa League that we play in this year. He’s a coach who knows what he wants and a coach who also progresses the players, and also old players like me. You never stop learning and this is very important. I’m really positive that we will do great things.
How would you describe your playing style?
My playing style? I’m a right back who likes to attack but I also know when it’s time to attack and when you need to stay behind. I have to put a balance between defence and attack.
At Juventus you won seven successive Serie A titles. How important is it to have someone of your experience in the dressing room, to guide some of the younger players?
I hope I can bring a lot of that mentality. It’s a little bit of the same project that I did seven years ago with Juventus. Juventus also, for two times, didn’t qualify for the Champions League. I hope I can bring a lot of experience, a lot of mentality and together, with my team, come back to the highest level of the Champions League.
You’re also the Swiss captain. You’re obviously seen as a leader in the dressing room. How important is it for you to be a voice, to help guide those younger players?
At the end it’s not too important to speak too much. The important thing is what you do on the pitch, that you are an example for the young players, for the old players, that everybody knows that this guy will help us. Like me also, I need to know that everybody helps me. This is the team spirit that we need to have, to have the confidence to give each other to help us.
