NBA star Giannis Antetokounmpo was given a surprise when hundreds of fans from his native Greece travelled to Cleveland to cheer him on in the Milwaukee Bucks’ defeat to LeBron James’ Cleveland Cavaliers.

The 22-year-old from Athens scored 40 points on the night but could not prevent Cavs from claiming a 124-119 victory.

Initially sceptical that the large section of fans at the Quicken Loans Arena were all from Greece, Antetokounmpo was stunned when they proved their credentials by singing the Greek national anthem.
