Arsenal boss Mikel Arteta admits he's worried about losing players to the Saudi Pro League.
The SPL transfer window is expected to run beyond the European deadline at the end of August.
Arteta said: "The window is still open so I prefer not to talk and say something! Because in this industry you never know.
"But I understand, it's another big competitor now and you see the amount of things that are happening there now and it's something for sure to be prepared for."
Thomas Partey has been in talks with SPL clubs this summer.
