The Serbia midfielder has returned to his first club, signing a five-year deal with the Swiss champions after spending two-and-a-half years at San Siro
Zdravko Kuzmanovic has left Inter to join Basel, the Swiss club have confirmed.
The 27-year-old, who was born in Switzerland despite representing Serbia at international level, started his career at Basel, joining at 16 and spending two seasons in the first team before departing to join Fiorentina.
Despite his contract with the Nerazzurri running until 2017, the midfielder has opted to return to FCB and expressed his delight after signing a five-year contract with the Swiss champions.
"It has always been my goal to come back to FCB one day," he said. "I'm happy that negotiations were concluded swiftly. I'm motivated and very ambitious and want to make my contribution to further success of Basel."
Club president Bernhard Heusler believes Kuzmanovic will improve the team and pass on his experience to the younger players in the squad.
"Throughout the years that Zdravko has spent abroad, we were in constant contact," he said. "We are getting an experienced midfielder at his peak. Moreover, he can set an example for the younger players in our team.
"I am delighted that the transfer has worked out and must thank Inter for their cooperation."
Kuzmanovic had joined Inter in January 2013 but only made 31 Serie A starts over that period as he struggled to make an impact.
