Following the Blaugrana's devastating exit from the Champions League after a 8-2 loss against Bayern, head coach Quique Setien lost his job and was quickly replaced by Ronald Koeman.
The Dutchman quickly undertook an evaluation of his squad and informed Vidal that he had no future at the club.
Barca are keen to get several veteran players off their wage bill, with Ivan Rakitic having already left for Sevilla and Luis Suarez set to depart also.

Joining Rakitic is now Vidal, who has joined Inter to link up with former Juventus head coach Antonio Conte, with the pair winning three Serie A titles in a row during their time together at the Allianz Stadium.
Vidal starred for Leverkusen in the Bundesliga before making the move to Italy where he enjoyed domestic success with Juve to eventually earn a move back to Germany with Bayern.
Now, he reunites with Conte as Inter will look to finally topple Juventus' league monpopoly.
