Graham Turner has spoken to the Worcester News on his hopes that he will be able to keep the basis of his squad for next season.
"They have all been offered new deals and we want them to stay," said Turner. "I think they will, but it would depend on what offers they get from other clubs.
"The number of players we can bring in will depend on who re-signs for us. We may be allowed to bring in six to eight players.
"We need to enliven the squad. I just feel we needed to change a few things and I think the supporters want to see new faces.
"The job over the next few weeks will be to try and bring in the right sort of players for the club."
"At the moment, we would need another goalkeeper, a central defender, but it depends on who we have next season because we are waiting on Tamika Mkandawire, Andy Tretton and Tony James.
"It's the same at full-back. Then we need a central midfielder, centre forward and so on. We need strengthening in most areas."
Talking about the four released players, Turner said:
"It's always difficult to make those decisions when you work with the players over the course of the season, and in Danny's (Williams) case for a long time. But decisions have to be made."
