The teenager set a BVB and Bundesliga record with his goal against Leverkusen on Saturday, becoming the first English player to score for the club and the youngest to score in the German top flight at 18 years and 27 days old.
He had an incredible overall performance on the day, dishing out two assists in the win, one of which was preceded by a remarkable bit of skill, with the player controlling a long ball with his heel at full speed.
Reus, who recorded a brace on Saturday, has admitted that he believes that Sancho is better than he was at 18.

The club's sporting director Michael Zorc seemed to agree with Reus' assessment. "Jadon was just outstanding for an 18-year-old," he declared.
