The seven time Serie A title victor signed as a free agent from the Italian giants after making more than 250 appearances for Juve. "Stephan will improve us on and off the pitch", Emery told Arsenal's official website.
Lichtsteiner will represent Switzerland at this summer's World Cup alongside his new Arsenal teammate Granit Xhaka, where he could win his 100th worldwide cap.
Attention immediately turns to who else will be coming through the doors, though it's pretty certain a deal for Borussia Dortmund centre-back Sokratis Papastathopoulos will be completed soon.
As for what attracted him to north London, Lichtsteiner said: "There is a project".More news: Genetic test could mean many women with breast cancer forgo chemotherapy
Lichtsteiner will challenge Spanish right-back Hector Bellerin for a spot in the Arsenal team next season.
The defender admits that taking the Gunners back into the Champions League is his goal as he feels a club of their size deserve to play amongst the elite of Europe. However, it's going to be a very busy summer (some would say it is already), and certainly an exciting transfer window at the Emirates, with a whole lot of topics to discuss. "The big objective is to come back on the highest level".
Lichtsteiner also added that he is unsure whether a decision will be finalized before or after the World Cup begins.
The defender hopes to help the Gunners to regain their reputation as one of the top clubs in Europe after a disastrous season past year when they finished sixth at the League table and failed to reach the Champions League.
