Bayern Munich have tweeted a picture of Chile international Arturo Vidal signing on the dotted line from Juventus for a reported £38m.
Bayern have not revealed any financial details of the deal that sees the 28-year-old arrive from last season's Champions League finalist on a four-year contract.
Vidal has experience of playing in the Bundesliga for Bayer Leverkusen, where he scored 15 goals during four seasons before leaving for Juventus in 2011.
Vidal helped Juventus to four consecutive Serie A titles during his time in Italy and the Coppa Italia last season.
