Tottenham are off the mark in the Champions League with a 3-1 victory this evening over Borussia Dortmund. Harry Kane scored a brace, while Son Heung-min also got on the scoresheet. The German club will feel unfortunate to be leaving without a point as they saw a strike from Pierre-Emerick Aubameyang disallowed for offside. The referee then sent off Jan Vertonghen at the death for a second bookable offence. The dismissal will have annoyed Mauricio Pochettino, but his side have the three points and more importantly have won at Wembley for the first time this season.
