The Foxes meet Arsenal later today.
Rodgers said: “What Mikel (Arteta) has recognised is the physicality in the Premier League. It's getting quicker and stronger each year.
“He's invested well, brought in good players and given them a good structure. They have a good base from which to play their game.
“They are very clear in their roles and how they play. He's given them good organisation, a good start point.
“Fundamentally, in order to attack well, you need to defend well – and that's key.
“They are clear on when to press or when to sit in their defensive block.
“Then they have that quality. In Pierre-Emerick Aubameyang, they have a world-class striker and there are others, too."
