Adel Taarabt and Bobby Zamora have been linked with moves away this week.
"You'll have to ask me at the end of the season because that's a hypothetical question," he said when asked if players would leave if they're relegated.
"From a player's point of view they have to just concentrate on the next eight games
"Then decisions on where their future might lie will be determined by where we finish in the league.
"If I feel players need to stay then that is what will happen. If they're contracted then it's my call."
