The 24-year-old midfielder has signed with the Cherries from Arsenal after demanding a loan move away from North London.
Wilshere missed most of last season with a leg injury and is determined to gain regular minutes which was unlikely to occur following the arrival of Granit Xhaka at the Emirates Stadium.
“We all wish Jack a successful season with the Cherries."
Bournemouth also posted a video of the deal taking place:
