Julian Weigl joins Borussia Dortmund from TSV 1860 Munchen

The rebuilding process is underway at the Westfalenstadion, as Borussia Dortmund completed the signing of teenage midfielder Julian Weigl from 2. Bundesliga side TSV 1860 Munich on Monday.

Weigl - a 19-year-old who is part of the German national squad currently competing at the U-20 World Cup in New Zealand - put pen to paper on a four-year contract and is Dortmund's second signing of the summer after sealing a summer deal for Gonzalo Castro.

"Julian Weigl is an exciting prospect for our central midfield," sporting director Michael Zorc said. "We see great potential in him."
