Swansea chairman Huw Jenkins admits the club could lose some key players before the new season starts.
Striker Jason Scotland and influential midfielder Ferrie Bodde are reportedly attracting the interest of Premier League duo Burnley and Bolton respectively, and Jenkins is particularly concerned that Scotland will not be around when the new season gets underway on August 8.
"It is a concern. No doubt it's difficult to try and fill those shoes if he did leave," he told BBC Wales.
"It's going to be very, very difficult for us to try and persuade him to stay but we will try and do that with the new manager's help.
"Everybody else seems quite settled and looking forward to meeting the new manager (Paulo Sousa) and working with him.
"Our aim is to keep as much of our squad together as we can and we can give Paulo the chance to start off next season."
