It is only the preseason but Gio Reyna is making a splash for Borussia Dortmund.

Case in point:

The U.S. youth international midfielder scored twice in the German Bundesliga club’s 11-2 win at Austria Wien Sunday.

Reyna, the son of former U.S. national team captain Claudio Reyna, found the net in the first half – in the ninth and 23rd minutes – before both teams changed their entire squads at halftime.

The 17-year-old Reyna’s brace came only days after he scored his first preseason goal against SCR Altach Thursday.

In case you are interested, Raphael Guerreiro, Immanuel Pherai, Jadon Sancho, Emre Can, Marius Wolf, Thorgan Hazard, Jude Bellingham, Taylan Duman and Nico Schulz also tallied for Dortmund.
