New Leicester signing Wilfred Ndidi could be handed an instant debut when the Foxes face Everton.
The midfielder completed a £15million move from Genk on Wednesday and signed a five-year deal with the champions.
Ndidi's work permit application has been accepted, he trained with his new team-mates on Thursday and boss Ranieri will decide if he is ready for the weekend.
Leicester go to Goodison Park in the FA Cup third round on Saturday and, while Ranieri said Ndidi was not a replacement for N'Golo Kante, he hopes he impresses quickly.
