Lucien Favre was left to rue Borussia Dortmund’s costly errors in Friday’s shock 2-1 defeat to FC Augsburg in the Bundesliga.
Die Borussen were handed their first league loss since December at the hands of 15th-place Augsburg following a superb brace by Ji Dong-won.
The South Korean winger put Augsburg in the 24th-minute before doubling their advantage in the second-half by chipping the ball over Dortmund keeper Roman Burki into the top right corner.
Former Barcelona striker Paco Alcacer struck late for Dortmund to score his 13th Bundesliga of the season.
But, at that point in the game, it proved to be nothing more than merely a consolation goal for Dortmund, who could see rivals Bayern Munich move level on points with them at the top of the Bundesliga should they defeat Borussia Monchengladbach today.
Speaking after the match, a frustrated BVB coach Favre bemoaned his side’s mistakes in what he felt was an unnecessary defeat.
“We could’ve won today. We had our opportunities to score goals but we didn’t take them,” said Favre on the club website.
“The opposition had practically no chances and yet we lost 2-1. Every mistake led to a goal. That’s a shame. We always want to win.
“We completely unnecessarily lost the match. We made a mistake, 1-0. But then we should’ve kept our calm and shouldn’t have made a second error.”
Prior to the match, Dortmund received a welcome boost in the return of captain Marco Reus after recovering from his thigh injury.
The German midfielder played 66 minutes of the game at the WWK Arena on Friday before coming off for Alcacer, but couldn’t make an impact to help Dortmund avoid defeat.
“It’s an extremely bitter defeat. We gifted them the goals through two individual mistakes,” said Reus.
“Then it’s obviously difficult to come back when you’re 2-0 behind. We had three or four good opportunities but then we made the individual errors and then they obviously set up camp in defence.
“We only have ourselves to blame, because you cannot give the ball away so easily and invite the Augsburg players to score goals. If you have a lot of possession, it’s important to get yourselves into the right spaces.
“We knew that Augsburg would cover a lot of ground, that they’d move a lot. We had enough opportunities to get the goals. We cannot allow such mistakes to happen or otherwise you’ll end the match on the losing side.”
