Leicester manager Nigel Pearson confirmed the Foxes are in talks with Esteban Cambiasso but is unsure if an agreement will be reached.
After a decade at Internazionale, the Argentinean left the Italian giants at the end of last season after his contract expired with the Leicester boss eager to add the 34-year-old's experience to his midfield.
"The only one that is in the public domain and has been for a couple of weeks is Esteban Cambiasso," Pearson told Sky Sports.
"We've not really made too much progress on that as things stand but I'm still hopeful something could be done.
"It may not be football issues. It's slightly more complicated than I'm prepared to discuss.
"Unfortunately at times it's quite a complicated process.
"It appears to be a case of various 'representatives' coming out of the woodwork so it's a case of getting to the bottom of who represents who and trying to achieve the goal, which is to add players to the squad.
The 51-year-old revealed that Leicester can only play waiting game with the Foxes determined to add at least one more player before the end of the summer transfer window.
"We'll have to see what happens," added the manager.
"If deals can be done and they are the right people then fine. I think it's fair to say we could do with one or two more players to give the squad more strength in depth."
