Partizan Belgrade have warned Tottenham off teenage talent Nikola Ninkovic.
The 17-year-old has already broken into the first-team with Partizan and is now attracting attention from across Europe.
"Any club which wants Nikola deserves our respect, but our point of view is very clear," Partizan's director of sport Ljubisa Tumbakovic told Sportski Zurnal.
"We want to build our team on young players so we want to inform everyone that Ninkovic is not for sale at the moment."
