Borussia Dortmund are so annoyed by fans, journalists and scouts being able to watch closed sessions from a hill next to their training ground that they have decided to buy it.

According to a report in German daily Die Welt, Dortmund have agreed a price of 326,000 euros ($346,749) for the mound of earth.

For years, fans have stood alongside scouts from other clubs and journalists, looking for a scoop on what has been dubbed 'spy hill', because it allows the public to watch their Borussia heroes train.

The club could do nothing about it as the land fell outside the training grounds they own.

Outsiders could still peek at coach Thomas Tuchel putting Dortmund's stars through their paces despite the club's efforts to plant trees and use banners to obstruct the view.
