Leicester City boss Claude Puel has claimed that it is "difficult to find a solution" against Manchester City.
On Tuesday night, the two clubs will lock horns in the EFL Cup quarter-finals and both teams are expected to make changes for the game at the King Power Stadium.
However, Puel has suggested that he is not optimistic about a result against Pep Guardiola's side, who sit 11 points clear at the top of the Premier League table.
The 56-year-old told reporters: "They are the top team in Europe. It's difficult to beat them, other teams have tried but without the results.
"With the ball and without the ball, they are the best at the moment. It's difficult to find a solution against them."
Man City ran out 2-0 winners when the teams met in the top flight last month.
