Erling Haaland continued his incredible season with a hat trick on his Borussia Dortmund debut, which sparked a comeback from 3-1 down to win 5-3 over Augsburg on Saturday.

The 19-year-old replaced Lukasz Piszczek on 56 minutes with Dortmund 3-1 down and had reduced the deficit three minutes later. On 61 minutes, Jadon Sancho equalised for the Bundesliga title hopefuls, and Haaland put Dortmund ahead on 70 minutes.

Haaland completed his hat trick on 79 minutes to make a second debut treble in his career, having also scored three on his Molde bow in 2017.

The Norway international, who joined from FC Salzburg earlier this month, has now scored hat tricks in the Austrian Bundesliga, Austrian Cup, Champions League and German Bundesliga, meaning he has netted a treble in all four competitions he has played in this term.

Florian Niederlechner had opened the scoring for the hosts on 34 minutes, before Marco Richter made it 2-0 just after the interval. Julian Brandt pulled one back for Dortmund on 49 minutes but Niederlechner made it 3-1 on 55 minutes.

Dortmund boss Lucien Favre reacted by bringing on Haaland, who changed the game. Dortmund are fourth in the table, four points behind leaders RB Leipzig, who play later on Saturday.
