Feyenoord chief Martin van Geel admits a move for Liverpool winger Oussama Assaidi or Arsenal's Ryo Miyaichi won't happen anytime soon.
The pair are loan targets, but Van Geel says they'll have to wait until the final days of the market for any chance of an affordable deal.
"Today, it is financially totally unfeasible," said Van Geel.
"We have to wait for the right moment, as we have done with Graziano Pelle and John Guidetti. Then it may be that they come, but we will not guarantee anything."
