Erling Haaland started his Bundesliga season with yet another fantastic performance as the 21-year-old Norwegian forward scored a brace and produced three assists in Borussia Dortmund's 5-2 thrashing of Eintracht Frankfurt at home on Saturday.

Marco Reus, Thorgan Hazard and Giovanni Reyna were Dortmund's other scorers.

Eintracht took some consolation from Felix Passlack's own goal in the first half and from Haaland's compatriot Jens Hauge's goal four minutes from time
