The Pole started 17 matches after joining fellow Polish goalkeeper and former Legia Warsaw team-mate Artur Boruc following his Bosman move from Dundee United.
Zaluska told his club's official website: "From a personal angle it has been a good season because I played 17 games, I played in Europe and was also involved in some important games in the league.
"I hope we're going to win something next season though. I'm sure we will win something and I also hope I'll be playing more games at the same time.
"But Artur is a legend here and that's why it's very difficult for me to play regularly. I'll have to wait and see what's happening next season but I know I'm ready to be number one. Nobody wants to be second keeper and that's why I work so hard every day."
