Bundesliga strugglers Freiburg have parted company with their coach Marcus Sorg only days before the team is due to regroup for training after the Christmas and New Year holidays. Sorg\'s contract has been terminated with immediate effect, with his assistant Christian Streich placed in charge, the club\'s director of sport Dirk Dufner confirmed at a press conference today. Freiburg sit at the foot of the table with just 13 points from 17 games so far this season, while they were knocked out of the DFB-Pokal in the first round by third division side Unterhaching. Sorg took over from Robin Dutt last summer after he left to replace Jupp Heynckes at Bayer Leverkusen. The 46-year-old becomes the fourth managerial change of the current Bundesliga season, following Michael Oenning of Hamburg, Ralf Rangnick of Schalke and Markus Babbel of Hertha Berlin.
