BERLIN (Reuters) - Borussia Dortmund's season is on the brink of collapse following their two defeats in two league games this year while coach Nuri Sahin is quickly running out of time to turn things around for last year's Champions League finalists.
Sahin, a former Dortmund youth and senior player, took over this season but has failed to make any real impact with his team having notched one win from their last six league games.
