BELGRADE, Dec. 9 (Xinhua) -- Serbian basketball champion Red Star narrowly overcame Olympiacos 81-76 in the 14th round of the Euroleague on Thursday in Belgrade, largely owing to a great performance of veteran Nikola Kalinic. Cheered by over 4,000 fans at the Aleksandar Nikolic Hall, the home team gained an early advantage, but the Greek team proved more experienced towards halftime and made a turnaround (36-38)
