The Dutchman brought in seven new faces this summer but a clutch of players – including Allan McGregor, Steven Davis, Scott Arfield, Alfredo Morelos, Filip Helander and Ryan Kent – are out of contract at the end of the season with Malik Tillman and James Sands’ loan deals expiring.
Van Bronckhorst, who revealed the recruitment of new players was a collective effort along with the scouting team, said: “It’s hard because you want to develop a team but at the end of this season I don’t know what’s happening with all the players.
“It could be that we have 10 new players coming in next year which will also mean you still have to develop again as a team to gel together.
“That’s also a thing we will have to wait and see how the team will look next season.
“You’re not deciding their future but they have their future in their own hands and it’s their decision because they’re out of contract. It can be 10, it can be less I don’t know.
“It’s dependent on how the coming months go but obviously, we have a lot of players out of contract.”
On who has the final say on new signings, Van Bronckhorst added: “You work with a list with the scouting team and there are also players that I follow myself. Due to various reasons you come to the players that we have brought in now.
"It’s not about who makes the final call. We make that call together. That’s the normal process. It’s always collective as we have one goal which is to be successful for this club. That’s how I’ve always worked. As coaches we always think short-term but the club has to think long-term with a vision for many years to come as coaches and players come and go.”
Asked whether he had been overruled in his attempts to make signings, the Rangers boss added: “Not overruled. We look at different positions, players coming in. And some players didn’t want to come or the transfer fees and salaries were too high. That’s a normal process. In an ideal situation you say I want this player or that player but in the end you also know you have to keep to our budget for salaries but also the budget for investing in players. That’s the policy and that’s important for the club for the future. You’re trying to get the best players in possible but I never get overruled for a player that I wanted to have and they’ve told me it’s impossible.
“I hope I don’t have to find 10 new players next summer but it’s football. Players go out of contract so you’re not deciding their future. They have it in their own hands when they are out of contract. So it could be 10 or it could be less depending on how the next months go.”
