Freiburg secured a 2-0 win against Wolfsburg in the Bundesliga on Friday, keeping their hopes of qualifying for the Champions League alive. Nils Petersen, who is retiring at the end of the season, scored his first goal of the season in the 75th minute to seal the victory for Freiburg. Christian Günter had earlier given Freiburg the lead with a deflected shot. Despite the win, Freiburg remained fifth in the league, just outside the four Champions League spots. They are level on points with Union Berlin, who play Hoffenheim on Saturday. Petersen has scored 105 goals for Freiburg since joining in 2015 and holds the Bundesliga record for most goals as a substitute with 34.
