"The Bundesliga is like that if Bayern comes or Dortmund then Bielefeld or Mainz they cannot react but there is a next level now yes, definitely and it is not great.

"I think this is part of the business and I am not sure if you can change that or if someone will change that but what makes it from a specific moment makes it not possible to deal with is our transfer window closes and the other transfer window stays open, so if they do not stop now then how can we react?

"From that moment we play until the first of January and this is our squad. That is what everyone is used to. And now we have that problem. We had it in the past with Russia if I remember right, it was a long time ago, thankfully, but they had a different transfer window and could still come [for players] but that was not completely crazy money."Saudi clubs have completely taken over the market, offering eye-watering wages and acquiring a plethora of household names.
