Bolton chairman Phil Gartside believes there could be big changes at the club this summer.
With a number of players out of contract and players returning to their parent clubs, there are likely to be several departures from the Reebok Stadium.
Striker Johan Elmander is one of the club's biggest out-of-contract stars and he is poised to join Turkish side Galatasaray.
Daniel Sturridge, who made a big impression during his loan from Chelsea, has left while Gary Cahill is being linked with a move.
Gartside has not seen much scope for upheaval in the past, but is now expecting big changes to manager Owen Coyle's squad.
"What happens is going to be dictated by who comes and who goes," explained Gartside.
"You've got the natural decisions where five players were out of contract, loan players who'll return to their clubs and then the speculation about whether someone is going to leave, or who to buy.
"It's probably going to be the biggest change here for quite some time.
"Owen inherited a settled squad with very few out of contract. There was little room for change.
"This year that is going to be totally different because there may be a lot of room if players leave.
"At this stage there are a lot of unknowns, ifs, buts and maybes. But I think there will be big changes."
