Croatia clinched its second Davis Cup by BNP Paribas title on a thrilling final day of action in Lille. 'It’s not every day that you become a world champion,” Cilic said. “For us it’s a dream come true. We are so passionate, you can see the fans are enjoying themselves. I feel that in Croatia it’s going to be incredible too. I thought Lucas started well in the first set and just a single point made the difference. After that I played better and served better. I’m extremely proud of my performance.'
