Werder Bremen striker Claudio Pizarro says he is committed to the club, even though he has not ruled out leaving at the end of the season. The Peruvian striker\'s contract expires in the summer and he has yet to commit himself to a new deal. After scoring his 12th goal of the season in yesterday\'s 4-1 triumph over Wolfsburg, he said his future is still open. \"You never know what might happen,\" he told Sky television. \"But I have a contract until the end of the season and we will then see where things go. Everything is possible. I could even stay, but I could also leave. Until then, I will do everything I can to make this a successful season.\" That is looking likely with Bremen\'s win moving them to within two points of the summit with one game to go until the midway stage of the season. That is a position opponents Wolfsburg could only dream about, as their ninth defeat of the season saw them slide closer towards the relegation zone. \"This match was just like in many games before - we played well up until we conceded a goal, and then we forgot to defend and hardly had a chance,\" said coach Felix Magath, whose target of a place in Europe next season is looking increasingly unrealistic.
