Swansea City have been told that they must be patient before completing a move for FC Twente striker Luc Castaignos.
The Premier League club are expected to sign the 21-year-old after agreeing a fee with their Dutch counterparts.
However, Swansea will have to wait for Castaignos to return from holiday before they can secure his services.
"It will be a while before things can be done," Twente chairman Joop Munsterman told Voetbal International. "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."
Castaignos scored 14 goals for Twente in the Eredivisie last season.
