Leicester have signed Bulgaria midfielder Radostin Kishishev from Charlton on a two-year deal.
Kishishev impressed during a loan spell at Leeds last season
The 32-year-old, who last season had a spell on loan at Leeds, is the sixth new arrival under boss Martin Allen.
"I watched him play against Belarus recently. I wanted to check he still had energy and enthusiasm - and he played well," said Allen.
"I'm delighted that he has agreed to come here. He gives us some steel in the centre of midfield."
Kishishev has been capped 59 times by his country and represented Bulgaria at the 1996 European Championship and the 1998 World Cup.
He joined Charlton in 2000 and made 149 appearances for the London club.
Kishishev will join up with his new team-mates for pre-season training on 2 July.
