Swansea City's deal for FC Twente striker Luc Castaignos remains on.
A fee for the 21-year-old frontman has been agreed.
Twente chairman Joop Munsterman told Voetbal International: "It will be a while before things can be done.
"The choice is up to the player. Only when Luc is back from vacation and is negotiating with Swansea can we expect progress. And as I have said, the clubs can work it out."
