The Borussia Dortmund boss has criticised the champions for making comments about the transfer situation of Marco Reus and says their conduct could come back to bite them

Borussia Dortmund coach Jurgen Klopp  has launched a thinly-veiled attack on Bayern Munich, saying that those who behave badly at the top will eventually pay the price for their actions.

The champions infuriated the 47-year-old this week after chairman Karl-Heinz Rummenigge talked openly about the transfer situation of Dortmund attacker Marco Reus.

And the Dortmund boss, whose team currently lie 15th in the Bundesliga with just seven points from their opening nine games, accused the current league leaders of kicking his club when they are down.

“In a period where both [teams] are at the top, it’s fun to reply to any [questions],” Klopp was quoted as saying by Bild , adding that he knows “nothing of what is going on right now” regarding the star’s situation.

“In our current position, where this causes relatively little enjoyment, it is just not worth it.

“However, I believe that life is fair. Whoever behaves badly while they succeed, can get payback [later].

“We currently do not have the problem of having to behave well during a period of success, because we are not in one,” he jokingly added.

Earlier this week Rummenigge had told Bild : “We know in Munich that [Reus] has a lot of quality. For us a young German national player of such quality is interesting. But I do not want to cause unrest in Dortmund.”

The war of words will add even more spice to an already mouth-watering clash between the two German giants at the Allianz Arena in the Bundesliga on Saturday.
