Borussia Dortmund seal summer deal for Gonzalo Castro

From the BayArena to the Westfalenstadion.

Borussia Dortmund announced the signing of Gonzalo Castro on Sunday, bringing an end to the midfielder's 16-year stint at Bayer 04 Leverkusen.

Castro, who is out of contract this summer and will therefore join Dortmund on a free transfer, put pen to paper on a four-year deal.

His impressive resume includes 285 Bundesliga appearances for Leverkusen, 25 goals, 20 Champions League appearances, and five caps for Germany's national team.
