Luton boss Rob Edwards is expecting more squad changes.
Edwards admits preseason will be crucial for their survival chances.
He told the club's official website: “We've got to prepare.
"There will be changes going on to the squad, there will be some leaving, there will be some more fresh faces coming in.
"Fitness is going to be important, building our way of playing, but then it all builds to a way of being ready for Brighton away and it doesn't come much tougher than that does it?"
