Bayern Munich CEO Karl-Heinz Rummenigge has cursed his side's luck during their 1-0 defeat at the hands of Borussia Dortmund.
A Robert Lewandowski goal gave the reigning champions a vital victory in their bid to retain their Bundesliga title in a tight affair at Signal Iduna Park.
The Bavarians had a string of chances to equalise after the goal, most notably when Arjen Robben missed a penalty, and Rummenigge feels that his side were unlucky to come out of the match without a point.
"It was an unfortunate unnecessary defeat," the 56-year-old told LIGA total! "I fear that we can't stop Borussia Dortmund from becoming German champions."
Despite conceding that Jurgen Klopp's side are now the likely victors in the league, Rummenigge urged the Bavarian club's players to put the defeat behind them as they pursue a place in the Champions League final.
"Tonight we mourn, but we are preparing for a important games with Real Madrid. We have to put in a top performance," he said.
Bayern Munich entertain Mainz on Saturday, before the first leg of the Champions League semi-final against Jose Mourinho's side on Tuesday.
