Manager Enzo Maresca says some Leicester City supporters are taking the dominance of the runaway Championship leaders for granted.
The Foxes beat Swansea 3-1 on Tuesday to move 10 points clear at the summit.
But the Italian's focus on possession and patient build up drew some shouts of criticism from the stands as fans demanded a more forceful approach.
"The only thing I can say is that people think it's easy, but it's not," Maresca said.
"I came to this club to play with this idea, the moment there is some doubt about the idea, the day after, I will leave, it's so clear.
