Wilfred Ndidi could quite possibly debut for Leicester City this weekend.
"Everything with the work permit is OK," said Ranieri.
"He trained today, he is available for Saturday and all is fine.
"Today was his first [training session]. He was OK and I want to see tomorrow and then I'll choose [the team for the weekend].
"He is a very impressive player with a great future. He is tall and jumps very well for the headers, moves the ball quickly, and recovers the ball very well.
"We have followed him a lot and we hope he will very quickly impress the fans.
"He's another kind of player [to Kante], totally different. A lot of big teams wanted him, but he prefers to come with us to improve."
