After the resignation of Gary van Egmond on Monday, former Sydney FC coach Branko Culina took over the role meaning the playing list will have to prove themselves over again.
"It was obviously disappointing to see Gary move on but I wish him all the best and hope he does well there (the Australian Institute of Sport)," Thompson said.
"As players, we now have to come back in and start work under Branko. He is a very experienced coach and I think you look at it as losing a good one (coach) but gaining a good one.
"Obviously Branko's been at the club a few months so the players know him but that was in a different role. As a coach, I'm sure he has his own ideas and it means everyone has to go out there and make an impression.
"It's positive in a sense that nobody can afford to be complacent (over selection) or be in a comfort zone."
