YOKOHAMA, Japan, June 30 (Xinhuanet) -- Ronaldo struck twice in the second half to give Brazil a 2-0 win over Germany and their fifth World Cup title.    After a goalless first half, the Brazilians took a 1-0 lead at the 67th minute when German goalkeeper Oliver Kahn was unable to hold onto a hard shot by Rivaldo just inside the penalty area.  Ronaldo ran in and pushed the rebound into the net.    Only twelve minutes later Ronaldo picked up a low cross from Kleberson and fired past Kahn from near the edge of the area for his eighth goal of the competition.    The German team, the obvious underdogs in the match, proved they were worthy opponents, especially in the first half.  They quite often caused turmoil in Brazilian defence with high balls and long range shots.    But the Brazilian team had the best chances.  Ronaldo missed two cleared chances in the first half while Kleberson hit the crossbar with a fierce shot.    Oliver Neuville came closest for the Germans but his free kick at the 49th minute hit the post after Brazilian goalkeeper Marcos managed to put a hand on it.    The win gave Brazilians their fifth World Cup title, after their wins in 1958, 1962, 1970 and 1994.    Ronaldo, who scored eighth goals in this tournament, totaled his World Cup goals to 12, level with legend Pele.  Enditem
