Leicester City are set to face Chelsea, Everton, Liverpool and Manchester City in the coming weeks.
Leicester are set to take on Chelsea, Everton, Liverpool and Manchester City in the month of December.
And Ranieri admits that the difficulty of their schedule presents the side with an obstacle that they will have to overcome.
"Now arrive Chelsea, Everton, Liverpool, Manchester City," Ranieri said. "That is a big problem for us, but now we must concentrate just on the next match. It is very important because I want to see how we play against big, big champions."
If Leicester can make it through December with an impressive set of results, it will confirm their credentials to remain at the top of the Premier League.
At the moment, the Foxes are two points clear at the top of the table, after making a remarkable start to the season.
Leicester have proven a threat to every side they have faced this season, and they have still only lost one match in the league.
The Foxes’ attacking quality has been very evident so far, and they are currently the top scorers in England’s top flight.
Ranieri’s side are certainly going into their most difficult run of games, though, and their title-winning credentials are set to be heavily tested over the coming weeks.
