Lichtsteiner had just 6 months left on his current deal with the Italian giants and reports of a move to the Premier League growing.
Juventus had become increasingly concerned at the reports, especially after initial talks of a new deal broke down.
United were believed to be the favourites with Louis Van Gaal being keen to add more experience to his current squad.
Mourinho and Wenger were also keeping a close on this the situation but will now be moving on after his current club confirmed that the Swiss International had signed a new two-year deal with the option of an extra year.
Litchsteiner has already won three Serie A titles and two Super Cups during his spell at Juventus.
