Bundesliga top scorer Pierre-Emerick Aubameyang grabbed the winner as Borussia Dortmund earned a 1-0 victory over battling Ingolstadt on Friday، Sky Sports reported.
Dortmund rode their luck to bag the win that sees them move onto 46 points from 25 games، three behind second-placed RB Leipzig and four ahead of Hoffenheim in fourth.
Leaders Bayern Munich، who are 10 points clear on 59، visit Borussia Moenchengladbach on Sunday. Leipzig travel to lowly Werder Bremen on Saturday.
Despite a lacklustre performance، Dortmund extended their unbeaten home run in the Bundesliga to 33 matches، with their last defeat dating back to April 4، 2015.
The hosts needed one moment of brilliance to win، with Gabon international Aubameyang slotting in beautifully with his left foot after a perfectly-timed cutback from Marcel Schmelzer in the 14th minute.
Dortmund، who face AS Monaco in the Champions League quarter-finals next month، lacked order at the back despite the return of central defender Sokratis Papastathopoulos.
They needed outstanding goalkeeping from Roman Buerki، especially in the first half when he denied Ingolstadt four times، including clearing off the line، to protect the lead.
Dortmund were even less aggressive after the break and failed to get a single shot on target، allowing Ingolstadt to reclaim the initiative.
But the struggling visitors، who are second-bottom on 19 points، seven from safety، could not find an equaliser، with Marvin Matip curling a shot wide four minutes from time and Mathew Leckie firing over with the last kick of the game.
