ZAGREB - Croatian champions Dinamo Zagreb won their fourth successive league title with two games to spare on Sunday after a 2-0 home win over Slaven Belupo Koprivnica put them seven points clear at the top. Dinamo have 73 points from 31 matches and will again finish ahead of their bitter foes Hajduk Split, who have 66 points after strolling to a 2-0 home win over Sibenik. Brazilian striker Sammir gave Dinamo the lead with a 10th-minute penalty after talented playmaker Milan Badelj was fouled by Slaven goalkeeper Silvio Rodic. Mario Mandzukic, who missed several sitters in the first half, doubled the lead shortly after the break when he took strike partner Ilija Sivonjic's defence-splitting pass into his stride and steered it past Rodic. Dinamo keeper Tomislav Butina was sent off in the 66th minute for a professional foul outside the penalty box but the champions held on comfortably to delight their fans on a warm evening. Dinamo can complete the domestic double on May 28, when they take a 3-0 cup final first-leg lead to Hajduk.
