Hamburg winger Piotr Trochowski unleashed a superb second-half winner as Low's side took a sizeable step towards claiming the single guaranteed place at South Africa 2010 from Group 4.
Their third win from four games, and three more points against a spirited Welsh side after last Saturday's 2-1 win over Russia, means Germany will finish the year on ten points, ahead of Russia and Wales who are on six. "With six points from the last two matches, we are absolutely content," said Low. "We are the group leaders, which is a good foundation to build on for next year. We expected the Welsh would defend deeply, but in the second-half we invested more and our team was mentally very strong."
Dogged defending by Wales frustrated Germany until Trochowski's strike, as the hosts' attack finally unpicked the lock on the Welsh goal when the 24-year-old rifled his shot past Welsh goalkeeper Wayne Hennessey. "We failed to score an early goal and made life a bit hard for ourselves," said captain Michael Ballack. "In the first-half, we lacked the concentration and a bit of finishing, but things were better in the second-half."
Trochowski chose the perfect time to score his first goal for Germany, but admitted his side should have finished with more goals. "We should have scored more goals - we certainly created the chances, but the main thing was to get the three points," said Trochowski. "It's been a while since I shot so many times on goal, the ball had to go in at sometime. I am just over the moon we won the game."
