Erling Braut Haaland resumed his stunning scoring run in the Champions League as Borussia Dortmund defeated Sevilla in the last 3-2.
They trailed early on to a Suso shot that deflected in off Mats Hummels.
It was 18 soon after via a neat finish, with Luuk de Jong hitting a late goal to give Sevilla hope in the tie.
There was a VAR check for a penalty for the Spanish side in added time for a potential foul by Thomas Meunier on De Jong but the video officials deemed the contact between the two legal.
The second leg in Germany is on 9 March.
