Gio Reyna produces superb assist for Erling Haaland in Borussia Dortmund's Champions League opener vs. Lazio

Gio Reyna came off the bench for Borussia Dortmund just after halftime and grabbed another assist when he found Erling Haaland all alone in the box to put his side on the board and back into the game in their opening Champions League group stage match against Lazio. 

The assist marks the 17-year-old's second in Champions League play and his sixth career assist for the Black-and-Yellow. It was also his fourth assist on the season, which is tied for second among players in Europe's top five leagues, behind only Tottenham's Harry Hane.

The assist ended up being for BVB's only goal in a 3-1 loss in Rome, although it continues to be an impressive October for the young American.
