Montenegro defender Stefan Savic has completed his transfer from Partizan Belgrade to Manchester City.
The 20-year-old becomes City's second defensive signing of the summer after they bought Gael Clichy from Arsenal.
Savic, who had a 10-day trial with the Gunners last year, has signed a four-year contract at Eastlands.
"I watch the Premier League all the time and I know it's the place to be, so I am looking forward to helping this club achieve great things," said Savic.
"We have an incredible stadium and I've seen how passionate the City fans are many times on TV.
It is a dream come true and I'm especially looking forward to meeting Edin Dzeko and Aleksandar Kolarov, because they both speak my language and come from the Balkans, too."
Savic played for Montenegro in their 0-0 draw at Wembley in October 2010 in a Euro 2012 qualifier.
He also faced English opposition when turning out for Partizan against Arsenal in the Champions League in December.
In February 2010, Savic, who was then playing for Serbian side BSK Borca, was reported as saying that he expected to sign a pre-contract agreement with the Gunners following his trial.
However, the deal did not go through and he joined Partizan in August.
