Liverpool boss Jurgen Klopp has called for the Saudi Arabian transfer window to come into line with Europe.

The Saudi Pro League operates to the long-standing dates of the Asian transfer window

But Klopp complained today: "I understand 100%, that is not comfortable and that it is not cool for us, but that is how it is.

"But if we want a player from, I don't know, Wigan Athletic (for example), I go there and they tell us the price and we probably pay it. Probably, it depends a little bit but not just us, big clubs in football. 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? We have a squad together now for the season that we try to keep together until next week [after the transfer deadline].

"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."

Klopp added: "It is new, it's challenging for everybody and we have to learn to deal with it, that is what I would say. But the authorities should make clear that if you want to be part of the system then you do your business at the same time like all the others at least. If we cannot change the rest then let's change that. I am pretty sure FIFA could do it like this (clicks fingers). I am not sure they want to but they could."
