Erling Braut Haaland made it seven goals in three games for Borussia Dortmund after scoring a double in Saturday’s 5-0 Bundesliga thrashing of Union Berlin while Bayern Munich went top of the table.

The 19-year-old, who signed from Salzburg, scored either side of half-time at Signal Iduna Park after being handed his first Dortmund start by coach Lucien Favre.

His tally is the most by any Bundesliga player in their first three matches.

Dortmund moved to third in the table, three points behind Bayern, who beat Mainz 3-1.

In Dortmund, 19-year-old England winger Jadon Sancho became the first teenager to score 25 goals in the Bundesliga when he started the rout with a looping shot past Union goalkeeper Rafal Gikiewicz.

Haaland added to his record run on 18 minutes when he was presented with a simple tap-in, before winning a penalty, which captain Marco Reus converted mid-way through the second half and Axel Witsel made it 4-0 on 70 minutes.

Haaland completed the rout when a Brandt back-heel fell into his path and he drilled his shot past the despairing Gikiewicz.
