Blackburn Rovers have signed Partizan Belgrade midfielder Radosav Petrovic for an undisclosed fee.
The 22-year-old has signed a four-year contract at Ewood Park after receiving a work permit.
The 6ft 4in defensive midfielder has made 19 appearances for Serbia, having made his debut for the country in August 2009.
Boss Steve Kean said: "Many European clubs were interested and we consider signing him a major coup."
Petrovic is currently with his international colleagues ahead of their friendly match against Russia in Moscow.
Kean added: "His record to date speaks for itself and he is exactly the sort of player we have been looking to recruit."
Blackburn face a race against time to make sure Petrovic is eligible for Saturday's Premier League opener against Wolves at home.
He is the club's second signing this summer, following Dundee United striker David Goodwillie to Ewood Park.
