"On top of that, both sides will benefit from this international exchange . The coaches can share valuable ideas and the young players can make new experiences and extend their horizons."
The Bayer 04 U17 team will take part in a training camp in Nagasaki once a year. The first time will be and the end of July/start of August 2018.

The agreement also covers the regular participation of Japanese talents in Bayer 04 U17 and U19 training sessions over a period of four weeks a year. The Nagasaki youth players will be able to take part in Leverkusen friendly games.
"In addition to the sporting aspects, this partnership also plays an important role in the internationalisation of the club. "We're confident this partnership will be have a broader base in future," said Florian Dederichs, head of brand and commercial management at Bayer 04 (pictured above right).
