Liverpool boss Jurgen Klopp has admitted concern over the spending of Saudi Pro League clubs.
Klopp also is worried that Saudi Arabia's transfer window will remain open after Europe's deadline.
"It is massive, in the moment," said Klopp on Saudi Arabia's influence.
"Pretty much the worst thing I think is that the transfer window in Saudi Arabia is open three weeks longer.
"If I am right, I heard something like that, then at least in Europe that's not helpful.
"Uefa or Fifa must find solutions for that. But in the end, at this moment, I don't know exactly what will happen.
"It is already influential, for us, for sure. We will have to learn to deal with it, and that's what we do.
"That's pretty much all I can say about it, time will show."
