The Chilean midfielder has agreed to join the Bavarians from Juventus, pending a medical - but where in Pep Guardiola's XI will he slot in?
When Bastian Schweinsteiger departed Bayern Munich for Manchester United earlier this month, it was obvious that the runaway Bundesliga champion would need to fill the iconic German's battling midfield role this summer.
It soon emerged that Pep Guardiola had pinpointed Arturo Vidal as the man to inherit Schweinsteiger's responsibilities - four years and four Scudetti wins after Juventus had beaten the club to the Bayer Leverkusen star's signature - and on Thursday Bayern confirmed that a deal is in place.
