Borussia Dortmund coach Jurgen Klopp was disappointed after his team lost 0-2 to Arsenal in the Champions League at the Emirates Stadium here.
"It took a while to get into the game. It was the worst possible start to concede such a quick goal. There were situations and moments where we were able to do what we wanted, but those moments were minimal. There were just too many times we weren't good enough, and Arsenal were deserved winners tonight," Klopp was quoted as saying by Xinhua.
"We will get better through work. That's the plan. We have to work. Work always works in life," he added.
French Under-21 international Yaya Sanogo (second minute) and Alexis Sanchez (57th) scored for Arsenal Wednesday.
