Erling Haaland scored a hat-trick of goals as Borussia Dortmund started the defence of their DFB Pokal title with a 3-0 win over hosts Wehen Wiesbaden on Saturday.

The Norwegian opened the scoring in the 26th minute after running on to a pass from Dortmund captain Marco Reus and doubled the lead from the penalty spot five minutes later.

Haaland went on to seal the win over German third-flight side Wehen five minutes into the second half, with 18-year-old Giovanni Reyna providing the assist for his team-mate's hat-trick goal.
