Sky Sports understands that Leicester are looking to start their summer transfer business early and have lodged a bid for Hull City's Robert Koren.
The Foxes invested heavily in their squad at the start of the 2011/12 campaign, but were unable to force their way into the Championship promotion picture.
Having missed out on a play-off place, they are now looking to piece together plans for next season.
Further additions are expected and manager Nigel Pearson has wasted no time in identifying possible targets.
He believes Hull midfielder Koren would be a useful addition to his ranks, having worked with the Slovenian during his time in the KC Stadium hot-seat.
It is understood that an offer has been put to the Tigers for a man voted their Player of the Year in a recent supporter poll, and the Foxes are now waiting on a reply.
