The Bulgarian is out of contract at The Valley this summer and it seems a host of clubs are interested in signing him.
Four clubs including Championship sides Leicester and Southampton are interested in signing Kishishev.
Leicester have reportedly tabled a one year contract for the midfielder but the players agent Tommy Langley has revealed that several clubs are looking at signing him.
Langley said: ‘There have been four clubs that have expressed an interest in Radostin.
‘Leicester are one of them to offer Radostin a deal to sign for them.
‘He is out of contract in the summer and he will wait and see what comes along.
‘There is interest from abroad too, but Radostin would prefer to stay in England as he is happy here.’
With Charlton being relegated the club are going to have to trim the wage bills and squad players like Kish will be shown the exit. Others linked to leave The Valley are Bryan Hughes, Marcus Bent, Luke Young, Darren Bent, Kevin Lisbie, Andy Reid and El Kakouri.
Expect a lot of movement to start in June when player`s contracts are up for renewal.
