Lucien Favre would have struggled to imagine his new star signing making a better start to life in the Bundesliga.

Favre called Erling Haaland “incredible” after the striker came off the bench to score a hat-trick against Augsburg on his Borussia Dortmund debut.

Inspired by Haaland, Dortmund rallied from a 3-1 down to record a 5-3 away win on Saturday that will live long in the memory.

The Norway international came on for Lucasz Piszczek after 56 minutes and netted with his first touch 183 seconds later with a low shot into the far corner.

Haaland doubled his tally with a tap in and got his third with a cool finish, with Dortmund’s creative trio Jadon Sancho, Thorgan Hazard and Marco Reus all getting an assist apiece.

The 19 year old joined Borussia Dortmund from Salzburg amid competition from Manchester United and a host of Europe’s top clubs.

“He moves well between the lines, which gives us another way of attacking. He was very good and did very well” Lucien Favre on Halaand.

Borussia Dortmund play Cologne on Friday.
