Borussia Dortmund captain Sebastian Kehl says he is not worried about his side\'s goalscoring problems as long as they keep winning games. While title rivals Bayern Munich appear to be scoring at will at the moment, Dortmund had to rely on a single goal to beat Werder Bremen yesterday and set a new league record of 20 games without defeat. The Westphalians could, and probably should, have matched the six goals that Bayern put past Hertha Berlin, but Kehl says the performances and the results are still spot on. \"Why should we be bothered?\" he said. \"We have not lost for 20 games in a row and as long as we win games and play as convincingly as we are now, then I am not worried.\" Dortmund\'s general manager Hans-Joachim Watzke last week claimed that he would be happy to finish second this season, even though his side currently have a five-point advantage over Bayern at the top of the table. Kehl, on the other hand, is more focused on winning the title for a second successive season. \"Of course we want to finish top,\" he told Sky. \"But we are not going to do that just by talking but by the way we play football. And at the moment, we are doing that very well.\" Werder now have a fight on their hands qualifying for Europe with Stuttgart closing in to within three points this weekend and Hannover able to reduce the arrears to a single point today. Their midfielder Clemens Fritz admitted his side were beaten before they even took to the field at the Westfalenstadion yesterday. \"We started from the very first minute without any courage,\" he said. \"We did not believe we could win it. We did not have the 100 per cent conviction that we could pick anything up.\"
