Krasner said: "We haven't finished yet. I won't discuss what's happening next week but there's a number of options."
Paul Robinson, Alan Smith and James Milner have already left, although Milner's departure in particular has concerned Whites fans the most.
Krasner wanted to make it clear that cutting costs at the club still had to be a priority.
He added: "This was the plan from day one. The wage bill was £40m last season, next season it has to be below £20m."
With Mark Viduka set to complete his move to Middlesbrough tomorrow, Dominic Matteo could be the next to leave, with Blackburn and Manchester City showing interest.
