Germany coach Joachim Loew is wary of taking on Serbia on Friday, when the opposition needs to at least avoid defeat to keep alive realistic hopes of reaching the second round at the World Cup. Germany was the most impressive of all 32 nations in the opening round of group matches with a 4-0 rout of Australia but Loew said he was considering one change in his lineup. "Even if you win, you can still think about one or two positions," Loew said. "I am thinking about one change but I'll leave it to my instinct tomorrow. "We have a lot of respect for Serbia and we expect a very difficult match. They have very good individuals, they are difficult to dispossess of the ball, they can dominate a game and they are always dangerous." Serbia defender Neven Subotic will replace the suspended Aleksandar Lukovic from the team that lost 1-0 to Ghana. Coach Radomir Antic said that Subotic was the "natural" replacement for Lukovic, who was sent off in the opener. Subotic was used as a substitute in that Group D match. Antic declined to give any other lineup details. "The loss makes them especially dangerous," Loew said. "If you know their mentality, you know they are capable of fighting until the last minute. It could be a physical game despite the technical abilities of both sides. Source: Yahoo sports
