The Japanese attacker has enjoyed a successful season at the King Power Stadium.
The Japan international forward has become a vital player for the East Midland side this year in their surprising mount on the Premier League title, scoring six games in all competitions.
The Foxes sit five points above closest challengers Tottenham Hotspur with four games still to play but could move an additional three points clear when then face Swansea City this weekend.
Okazaki has become a fan favourite at the King Power Stadium due to his endless work-rate, energy and first-team contribution. It is interesting to note that the former Stuttgart playmaker has been substituted in 22 of his 25 Premier League starts this year due to the energy he exudes in every match.
But Leicester head coach Ranieri claims Okazaki should now become an even better player after passing his English test earlier this week. The Italian joked in his pre-match press conference that before Okazaki received confirmation, he was unable to understand what Ranieri was saying.
