Klopp’s side have a terrible recent record of seeing players join their main rivals with Mario Gotze’s transfer followed by Robert Lewandowski’s decision to snub a new deal and link up with Pep Guardiola.
It now appears that Dortmund are losing the race in terms of being the ideal club for German youngsters to develop at, as the 16-year-old Felix Gotze has been tempted into a move away.
While the loss of Felix isn’t a direct blow for Dortmund’s first team chances of success this coming season, it will annoy the manager and could cause him to be uptight over more players leaving, at any level, over the rest of the summer.
BVB have some of the best youngsters and first team stars in the modern game with Manchester United thought to be looking at Mats Hummels while Arsenal have been linked with Sven Bender as well as his brother Lars at Bayer Leverkusen.
Ultimately Dortmund’s chances of getting back to the top of German football are going to be improved if they are able to keep their key players and their best youth team prospects.
What will most likely be the bitterest part of this news is that Mario is more than likely to have played a big role in persuading his brother to make the move.
There is still a great deal of hard feeling over the transfer of Mario to Bayern Munich, which will only be increased as he’s likely to have urged his bother to jump from the Dortmund ship.
The biggest loser in all of this is Klopp as he’ll be petrified that as soon as his youth team stars show anything like positive progress, they’ll be attracted away from his club.
Arsenal and Manchester United could also miss out if this forces him to prevent anyone else from leaving the club this summer, whether it’s to a direct rival or not.
