Bolton have not offered new deals to Ivan Campo, Stelios Giannakopoulos and Andranik Teymourian, but Gary Megson is keen for Jussi Jaaskelainen and Ricardo Gardner to stay at the club.
Jaaskelainen and Gardner are both out of contract in the summer and have been linked with moves away from the Reebok Stadium.
However, Megson is hoping to persuade the long-serving duo to sign new agreements after Bolton clinched their Premier League survival.
"Jussi and Ricardo have both been excellent servants and are still very much part of my future plans for this football club," Megson told the club's official website.
"Hopefully we can get them secured on new deals as soon as possible."
Giannakopoulos and Campo have been with Bolton since 2003 but they are now free to move elsewhere after falling down the pecking order in recent months.
Megson has also decided there is no future for Iranian midfielder Teymourian at Bolton.
"Ivan, Stelios and Andranik have all done well for Bolton Wanderers and I'd like to express my gratitude to them," said the Trotters boss.
"It's time for them to move on and I wish them all the best."
