Belgium international De Bruyne was in fine touch to help City to a 3-1 win over the Foxes.
"Kevin is unbelievable," said Rodgers. "He's a world-class player and, with world-class players, they'll find the space.
"You can block up spaces and be tight and organised, but the world-class players will find the space.
"It's his level and mentality. To see it live, at that level and with that quality, was absolutely great.
"You have a plan but it's very, very difficult, because he executes it in every game he plays. David Silva is the same. Their in-built brain for football finds the space and they have that quality to hurt you."
